Pellagra, also known as niacin deficiency, does not strictly present with three classic symptoms. However, it may manifest with symptoms such as dermatitis, diarrhea, and dementia. The details are analyzed as follows:
1. Dermatitis
Niacin deficiency is primarily caused by insufficient levels of niacin (vitamin B3) in the body. Skin lesions typically appear symmetrically on exposed areas of the limbs. Initially, the affected skin becomes red and itchy. As the condition progresses, it may lead to oozing wounds and peeling skin.
2. Diarrhea
After developing niacin deficiency, digestive and absorptive functions may weaken and gastrointestinal motility may slow down, leading to diarrhea.
3. Dementia
If niacin deficiency is not treated promptly and the condition worsens, it may adversely affect the brain's nervous system, causing hippocampal atrophy, which can subsequently trigger dementia.
In addition to the above symptoms, patients may also experience menstrual disorders, amenorrhea, urethral burning sensation, and decreased libido. If diagnosed with niacin deficiency, individuals should seek timely medical evaluation and proper treatment at a reputable hospital to promote recovery.
