Dear Jereez Xean Junio Maningding

This is mainly because most diabetics need to use drugs to control blood sugar, and some even cannot control blood sugar with drugs. No matter which of these two, their blood contains drugs or excessive sugar. Moreover, this does not meet blood donation requirements, so people with diabetes are not recommended to donate blood.

Type 1 diabetic

Insulin injections for life are mostly not acceptable. Only people with diabetes in the honeymoon period can control blood sugar well without injecting insulin. People with type 1 diabetes who are in the honeymoon period can consider donating blood.

Type 2 diabetes

It is not suitable if people are taking medicine or injecting insulin. Those with poor blood sugar control are also inappropriate. The more suitable one is "streaking," but for people with diabetes whose blood sugar is still well controlled. They do not need to take medicine and rely on diet and exercise to control blood sugar well. They may consider donating blood.

In summary, only people with diabetes whose blood sugar can fluctuate within the normal range without relying on drugs can consider donating blood.

At present, I have not found the influence of DM patients on themselves after donating blood (except for too many blood donations and too close cycles)

However, it should be noted that sugar friends who use insulin cannot donate blood because the blood recipients are not necessarily adults. They may be teenagers or infants. If the sugar friends who have used insulin donate blood, the residual insulin content in the blood cannot be assessed; if the blood recipient is a small child, it may cause hypoglycemia hazards.

Hope this can help your research.
