Our immune system is an essential part of our survival. Many habits can weaken the immune system; sleep deprivation, lack of exercise, feeling lonely and stressed, eating processed/fatty foods, the overuse of antibiotics, drinking/smoking and being overweight can all contribute to a lowered immune response. According to the American Psychological Association, a report explains that long-term stress weakens the responses of our immune system. Stress decreases the body's lymphocytes, which are the white blood cells that fight off infection. So the lower the levels of lymphocytes, the more you are at risk for viruses like the common cold.

Our immune system might be compromised if you are experiencing frequent diarrhea. Understandably so since nearly 70 percent of our immune system is located in our digestive tract. Research shows that beneficial bacteria and microorganisms live in the gut to defend it from infection and support the immune system. A low amount of these microorganisms can leave us at risk to viruses, chronic inflammation and even auto-immune disorders.

We've all gotten scrapes, bruises and cuts. All that nutrient dense blood goes to the injury to repair and regenerate new skin. Although, if the wounds linger and take a long time to heal, it could signify a problem as the immune cell response comes from a healthy immune system.

Hi Dr Manal Hadi Kanaan . Frequent and recurrent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections. Inflammation and infection of internal organs. Blood disorders, such as low platelet counts or anemia. Digestive problems, such as cramping, loss of appetite, nausea and diarrhea.. See the link : https://www.mayoclinic.org/diseases-conditions/primary-immunodeficiency/symptoms-causes/syc-20376905

Thanks a lot, Dr. Aqeel yousif Alshukri really thanks...My sincere gratitude, Doctor.

Thanks a lot, Dr. Aref Wazwaz really thanks...My sincere gratitude, Doctor.

Dr. Manal Hadi Kanaan excellent question. I apologize if I am about to offend anyone but most of what you describe especially inflammation, anemia, and infections is the daily experience for 90% of Americans. That is the percentage of those who are overweight and certainly the case for the 40% obese. These numbers are comparable in Saudi Arabia, Canada, Mexico, Brazil, with India and China closing up the gap. In a nation with the first and most extensive iron fortification program on our planet, the United States anemia is a growing problem because of the increased prevalence of anemia (4.0% to 7.1%) and moderate-severe anemia (1.0% to 1.9%), which nearly doubled from 2003–2004 to 2011–2012.Article The Prevalence of Anemia and Moderate-Severe Anemia in the U...

So basically, I would suggest that you are immune-compromised if you have any of the so-called autoimmune diseases like Obesity, Diabetes, Cancer etc. which if you believe in the leaky gut syndrome is a sort of internal infestation of microbiota outside the constraints of the intestinal tract.

Aqeel yousif Alshukri & Chinaza Godswill Awuchi Nota Bene: not to have colds for three to five years was considered a warning sign for cancer because anecdotally cancer patients were so surprised to learn they had cancer exclaiming "but I have not had a cold for years and years."

I think the main symptom of weakened immune system is susceptibility to infection, meaning frequent infections.

Low immunity comes hand in hand with poor functioning of the systems in your body. You start to have frequent headaches , you feel exhausted, poor circulation which leads to cold hands,constipation or diarrhea,dry and yellow eyes,hair loss, rashes or infections like candidiasis among others

We can have antibody titer test. An antibody titer is a type of blood test that determines the presence and level (titer) of antibodies in the blood. This test is carried out to investigate if there is an immune reaction triggered by foreign invaders (antigens) in the body.

Antibodies or immunoglobulins are specialized proteins produced by the immune system to identify and destroy foreign invaders, such as bacteria and viruses. An antibody titer blood test is done to determine the presence (qualitative) and amount (quantitative) of antibodies in the blood.

Source: https://www.news-medical.net/health/What-is-an-Antibody-Titer.aspx

Tired

Each of us feels tired at a certain moment of the day, after doing a certain physical or intellectual effort, but feeling tired and exhausted throughout the day and only wanting to go to bed and sleep may be a sign of a weak immune system.

More vulnerable to viruses and bacteria

The German "Fundang Vibe" website reported that susceptibility to infection with viruses and bacteria is one of the signs of a weak immune system, as infection with viruses and bacteria always makes the human body vulnerable to different types of diseases, and thus enters it into a cycle of continuous suffering.

the disease

The body itself is often able to fight the pathogens, as it has the ability to overcome the disease and recover, but suffering from a serious illness may often be a sign of a weak immune system, according to the same source.

Okay, maybe seeing is believing. There is a link between metabolic syndrome diseases and a weakening immune system. Look at the prescription and obesity maps, you do not need high level statistical analysis to see the relationship. If you have a fat roll around your waist you have a weak immune system.

At least 80 illnesses are caused by immune system problems. They can all cause inflammation. But there are other warning signs, Keeping in mind that these possible clues can happen for many other reasons. They are:

1. Cold Hands

If your blood vessels are inflamed, it can be harder for your fingers, toes, ears, and nose to keep warm. The skin in these areas may turn white, then blue, when you’re exposed to the cold. Once blood flow returns, the skin may then turn red.

Doctors call this “Raynaud’s phenomenon.” Immune system problems can cause it, but so can other things, including smoking, some prescription drugs, and conditions that affect your arteries.

2. Bathroom Problems

Diarrhea that lasts more than 2 to 4 weeks can be a warning sign that your immune system is harming the lining of your small intestine or digestive tract.

Constipation is a concern, too. If your bowel movements are hard to pass, very firm, or look like they’re made up of small rabbit pellets, your immune system may be forcing your intestine to slow down. Other possible causes include bacteria, viruses, and other health conditions.

3. Dry Eyes

If you have an autoimmune disorder, that means your immune system attacks your body instead of defending it. Rheumatoid arthritis and lupus are two examples.

Many people who have an autoimmune disorder find that they have dry eyes. You might feel a sandy, gritty feeling like something is in your eye. Or you may notice pain, redness, a stringy discharge, or blurred vision. Some people find they can’t cry even when they’re upset.

4. Fatigue

Feeling extremely tired, like you do when you have the flu, could mean something’s going on with your body’s defenses. Sleep is unlikely to help. Your joints or muscles can ache, too. Again, there could be many other reasons why you feel this way.

5. Mild Fever

If you’re running a higher temperature than normal, it could be that your immune system is starting to overwork. That can happen due to an oncoming infection or because you're starting to have a flare of an autoimmune condition.

6. Headaches

In some cases, headaches can be related to the immune system. For example, it could be vasculitis, which is inflammation of a blood vessel caused by an infection or autoimmune disease.

7. Rash

Your skin is your body’s first barrier against germs. How it looks and feels can reflect how well your immune system is doing its job.

Itchy, dry, red skin is a common symptom of inflammation. So is a rash that is painful or doesn’t clear up. People with lupus often get a butterfly-shaped rash across their nose and cheeks.

8. Joints Ache

When the lining inside your joints becomes inflamed, the area around them is tender to the touch. It might also be stiff or swollen, and it can happen with more than one joint. You may notice that it’s worse in the morning.

9. Patchy Hair Loss

Sometimes the immune system attacks hair follicles. If you lose hair on your scalp, face, or other parts of your body, you could have a condition called alopecia areata. Strands or clumps of hair coming out can also be a symptom of lupus.

10. Repeated Infections

If you need to take antibiotics more than twice a year (four times for children), your body may not be able to attack germs well on its own.

Other red flags: Chronic sinus infections, being sick with more than four ear infections in a year (for anyone over the age of 4), or having pneumonia more than once.

11. Sensitive to Sun

People with an autoimmune disorder sometimes have an allergic reaction to ultraviolet (UV) rays called photodermatitis. You may get blisters, a rash, or scaly patches after being in the sun. Or you may get chills, a headache, or nausea.

12. Tingling or Numbness in Your Hands and Feet

It can be completely innocent. But in some cases, it can mean that your body is attacking nerves that send signals to your muscles. People who have Guillain-Barre syndrome, for instance, may have numbness that starts in their legs then moves up to their arms and chest.

Chronic inflammatory demyelinating polyneuropathy (CIDP) has symptoms similar to the demyelinating form of GBS (called acute inflammatory demyelinating polyneuropathy, or AIDP), but while GBS lasts two weeks to 30 days. CIDP lasts much longer.

13. Trouble Swallowing

If you have a tough time getting food down, your esophagus (the tube that carries food from your mouth to your stomach) could be swollen or too weak to work well. Some people feel like food is stuck in their throat or chest. Others gag or choke when they swallow. One of the possible causes can be a problem with your immune system.

14. Unexplained Weight Change

You find yourself gaining extra pounds even though your eating habits and workouts haven’t changed. Or the number on your scale may drop for no clear reason. It's possible this is because of damage to your thyroid gland from an autoimmune disease.

15. White Patches

Sometimes your immune system decides to fight the skin’s pigment-making cells, called melanocytes. If so, you’ll start to see white patches of skin on your body.

16. Yellowing of Your Skin or Eyes

Called jaundice, it may mean that your immune system is attacking and destroying healthy liver cells. That can lead to a condition called autoimmune hepatitis.

Dear Dr. Ahmed T. Hussein really thanks...My sincere gratitude, Doctor.

Ahmed T. Hussein great standard answer "At least 80 illnesses are caused by immune system problems. They can all cause inflammation". Your answer is the State of the Art. Unfortunately, I believe our understanding of autoimmune diseases to be completely wrong and backward. The human body does NOT mysteriously attack itself (No other wild animal on our planet does either) It is under attack by microbes!!! Here is a list of common autoimmune diseases: celiac disease, diabetes mellitus type 1, Graves' disease, inflammatory bowel disease, multiple sclerosis, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. I am going to take the last systemic lupus erythematosus and add the keyphrase leaky gut and the first result is Article Recent Advances in Our Understanding of the Link between the...

Please Ahmed, do this search to any of your 80 inflammatory diseases from heart disease to obesity and you will find leaky gut and microbes. The immune system is inflamed by an infestation of microbes like inside arterial plaques to viruses attacking the beta cells in the pancreas(diabetes mellitus type 1).

So why now? Well, iron is linked to inflammation and I think it is no coincidence that our food is being systematically enriched with iron: http://yukna.free.fr/science/medical/iron/Fortified-Iron.php

And of course, pathogens need energy-rich hosts and the food industry is lacing almost everything with sugar. I believe it is no coincidence that Nipah Virus and Malaria outbreaks are positive linked to sugar plantations for local consumption and export.

While I am trying to write the pertinent articles to individually explain this to all my colleagues, it is long and hard work and for the moment these conclusions are only available on this wonderful thread by Manal Hadi Kanaan

Apart from the pertinent analysis, there are indicators even in neonates (the one that the expected jaundice of the newborn does not appear; those known as "bubble children" with Innate Immunodeficiency Syndrome; therefore, HIV generates the Acquired Immunodeficiency Syndrome - AIDS-, etc). But some "low" levels -in the analytics- of markers of the Immune System are idiopathic and idiosyncratic, normal statistical deviations, and do not correlate with a greater vulnerability to infections.

Weakened Immune Systems During COVID-19:

https://www.rush.edu/news/weakened-immune-systems-during-covid-19

I think the most important signs

It is the ease of exposure to any pathogen

Dear Dr. Manal Hadi Kanaan ,

White blood cells, lymph nodes, and antibodies comprise the immune system, which aids the body in protecting itself from external illnesses. The five leading indicators of a weakened immune system are excessive stress, recurrent infections, tiredness, slow wound healing, and joint discomfort.

Frequent colds, infections, digestive issues, delayed wound healing, skin infections, exhaustion, organ problems, delayed growth, a blood abnormality, and autoimmune illnesses are all signs of a weakened immune system. The immune system defends the body against diseases and other dangers in the environment.

Focal Q.

Immunity is represented as whole system constant Capacity. This system possesses many units or parts. If one part is effected, the other will be too. For instance, if someone had seasonal allergy, he would sneeze, His eyes tear, His Temperature would maximize.

Manal Hadi Kanaan I just posted an article on How Covid Vaccines might protect patients I thought I would share the abstract with everyone here to see what they think.Preprint Without conferring immunity How do Covid19 vaccines actually...

Abstract:Covid19 is leaving devastated immune systems behind with a distinct pattern of excess mortality in deaths from cardiovascular conditions, liver disease, and diabetes etc. Bizarrely, mRNA vaccines do not confer natural immunity, and worse while protecting patients from more serious forms of Covid19 cases also appear to damage the immune system with the same pattern as Covid19. Since SARS-CoV-2 is a retrovirus and like viral phages can integrate into the genome of the infected cell and be expressed as chimeric transcripts fusing viral with cellular sequences, also has interaction with bacterial products, could this virus also exist in a lysogenyo stage and hijack bacterial quorum sensing (QS) autoinducer (AI) and thus collect information to transmute between lysis (virulent) and lysogenyo (temperate) phases? Then, sinceCovid19 vaccines are highly effective at preventing COVID-19-related morbidity and mortality,.could it be possible that mRNA therapies fool this sophisticated virus into thinking that the patient has already been infected and morph into a wait and see stealth lysogenyo mode?

Immunodeficiency disorders weaken the immune system, allowing infections and other health problems to occur more easily. One of the most common indicators of immunodeficiency is infections that are frequent, last for longer periods of time, or are more difficult to treat, compared to someone with a normal immune system. You may also get an infection that someone with a healthy immune system wouldn't

Dear Dr Manal Hadi Kanaan , in this pandemic, it seems there are a lot of misunderstandings about immunity. Actually, immune system is a big privilege of human as multicellular organism over microorganisms. No matter how weak or compromised the immune system is, most immunocompromised persons is still able to efficiently clear the microorganisms like SARS-CoV-2:

Article Persistence and Evolution of SARS-CoV-2 in an Immunocompromised Host

https://www.science.org/content/article/cancer-survivor-had-longest-documented-covid-19-infection-here-s-what-scientists-learned

Also, Pediatric Patients with Primary Immunodeficiency (PID) cope with COVID-19 very well:

Article Assessment of COVID-19 Incidence and the Ability to Synthesi...

Conclusion of this investigation: "In the study group (Pediatric Patients with PID), in most cases the disease had a mild and self-limiting course. Remarkably, even though IgG deficiency was the most prevalent form of PID in the study group, the patients were able to respond satisfactorily to the infection in terms of anti-SARS-CoV-2 IgG."

Also, it is evident that human innate immunity plays the dominant and decisive role in the clearance of the SARS-CoV-2 viral infection, and making the viral infection self-limiting. When there is viral or bacterial infection, the human innate immunity will trigger cell necrosis or necroptosis, an inflammation-inducing immune response featured by violent cell self-destruction:

Article Necroptosis in anti-viral inflammation

Article From Cell Death to Regeneration: Rebuilding After Injury

By such a violent cell self-damage, all the microorganisms in the infected cells are also destroyed, so that most microbial or viral infections are self-limiting.

This self-destructive inflammatory feature shows that human immune system is not a protecting or defending system at all. Rather, it is a professional killer and rebuilder. It will destroy any body cells that are damaged or not properly functioning, thus clear any non-welcomed invader as a side effect.

The real challenge for the immune system is, how to effectively and swiftly remove the debris of the destroyed cells, so that the debris will not trigger subsequent hyperinflammation and cytokine storm, and initiate the tissue regeneration process.

Most of the common diseases, including the severe cases of current COVID-19, are the overreaction of this self-destructive violent immune response, as Sir William Osler stated more than 100 years ago: "Except on few occasions, the patient appears to die from the body’s response to infection rather than from it. Sir William Osler (1904)": (copied from "Living in a Hostile World: Inflammation, New Drug Development, and Coronavirus"):

sign by increase and repeated infection

People with a weak immune system have a higher risk of experiencing frequent infections and severe symptoms. The primary symptom of a weakened immune system is susceptibility to infection. A person with a weakened immune system is likely to get infections more frequently than most other people, and these illnesses might be more severe or harder to treat. These individuals may also find themselves dealing with an infection that a person with a stronger immune system would not get.

https://www.medicalnewstoday.com/articles/324930#signs-and-symptoms

Signs of a weak immune system include frequent cold, infections, digestive problems, delayed wound healing, skin infections, fatigue, organ problem, delayed growth, a blood disorder, and autoimmune diseases.

According to MedicineNet, signs of a weak immune system include frequent colds, infections, digestive problems, delayed wound healing, skin infections, fatigue, organ problem, delayed growth, a blood disorder, and autoimmune diseases.

Some of the early warning signs of weak immunity include frequent infections and severe infections that are difficult to treat. Other signs include frequent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections. Frequent joint aches are also one of the biggest tell-tale signs of weak immunity. High-stress levels can also decrease the effectiveness of the immune system in the long term.
