With this condition, a wound (often in the feet) does not heal well due to diabetes. Diabetes weakens circulation and the immune system resulting in poor wound healing. Diabetes also decreases sensation in the extremities so people often do not have pain or notice the tissue until it is completed dead. The tissue becomes black and dry appearing as it completely dies off. This wound may also become a source of infection leading to spread of infection to other parts of the body.
Your doctor may ask these questions to check for this disease:
Surgery is needed to remove the gangrene portions and those that may have become infected. Antibiotics are often to treat infection. Although dead tissue cannot be saved, good blood sugar control is critical to preventing future episodes.

My experience was great. I was worried, but the symptom checker helped me narrow down what it might be. I feel a little relieved compared to when I first started, and it gives me a starting point for what my symptoms could mean.

Male, 50s
The questions asked and possible causes seemed spot on, putting me at ease for a next-step solution.

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
