Chronic Illnesses
Certain medical conditions would impair your sense of taste and increase the risk of developing dysgeusia. These include nerve damage, dementia, stroke, diabetes, Parkinson’s disease, and GI disease. Dysgeusia is especially common in diabetic patients, especially those with type 2 diabetes mellitus. In fact, taste issues can be an early sign of the condition due to fluctuated levels of blood sugar. [4]
