Niacin deficiency neuropathy

Nicotinic acid generally refers to nicotinic acid, nicotinamide, and other biologically active pyridine derivatives. Nicotinic acid deficiency is also known as nicotinic acid deficiency, also known as pellagra (pellagra) and Pellagra disease. Nicotinic acid deficiency was found to be the cause of the disease in 1937. The human body can synthesize endogenous niacin, but exogenous intake is necessary to avoid niacin deficiency. The occurrence of this disease is related to niacin, nicotinamide, tryptophan intake, reduced absorption and metabolic disorders. It is a chronic wasting disease, with dermatitis, dementia, and diarrhea as the main clinical symptoms.
