Tareq Abdhilkadhim Naser Alasadi , I think that since we cannot live without water longer than 3 days, we can settle that there is no life without it. If it's necessary to survive (even for healthy people), you really can't consider that a drug. Also, your point about weight loss is misinformed, it's not that drinking water instead of soda can help with weight loss, is that soda is the reason of the weight gain. It is a bit like saying that chewing gum instead of smoking a pack a day can help lower your risk of lung cancer...This is not a treatment, this is a basal state.

Dear Marie ,my great friend thank you for your comments ,i agree with you ,but still think as water is important as good as drugs ,why?,for many reasons, er is needed for most body functions, including to:

• maintain the health and integrity of every cell in the body
• keep the bloodstream liquid enough to flow through blood vessels
• help eliminate the byproducts of the body’s metabolism, excess electrolytes (for example, sodium and potassium), and urea, which is a waste product formed through the processing of dietary protein
• regulate body temperature through sweating
• moisten mucous membranes such as those of the lungs and mouth
• lubricate and cushion joints
• reduce the risk of cystitis by keeping the bladder clear of bacteria
• aid digestion and prevent constipation
• moisturise the skin to maintain its texture and appearance
• carry nutrients and oxygen to cells

Dear Tareq, what you are describing are some of the reasons why water is essential to life. There can be no life without water, so it's quite normal that many/all bodily functions require it to be healthy

As prevention of some health problems such over weighting, diabetic, Gastric, nephritic syndromes and dyspepsia the warm clean water without medicine has perfect affect.
