Pellagra is a condition caused by a deficiency of niacin (vitamin B3) in the diet. Signs and symptoms of pellagra include:
1. Dermatitis: Pellagra often presents with a characteristic rash on areas of the skin that are exposed to sunlight, such as the hands, feet, neck, and face. The rash is typically red, scaly, and may be accompanied by itching and burning.
2. Diarrhea: Individuals with pellagra may experience frequent bouts of diarrhea, which can lead to dehydration and electrolyte imbalances.
3. Dementia: Severe cases of pellagra can lead to neurological symptoms, including confusion, memory loss, disorientation, and hallucinations.
4. Depression: Pellagra can also cause mood changes, such as irritability, anxiety, and depression.
5. Weakness and fatigue: Individuals with pellagra may experience weakness, fatigue, and muscle pain due to the lack of energy production from niacin.
6. Glossitis: Inflammation of the tongue, known as glossitis, can occur in individuals with pellagra, leading to pain, redness, and swelling of the tongue.
7. Anorexia: Loss of appetite and weight loss are common symptoms of pellagra, as the body struggles to absorb nutrients properly.
If left untreated, pellagra can progress to more severe complications, including organ damage and death. It is important to seek medical attention if you suspect you may have pellagra or are experiencing any of these symptoms.

Signs and Symptoms of Pellagra
Pellagra is a condition caused by a deficiency of niacin (vitamin B3). It typically affects individuals who have a poor diet, such as those living in poverty or with restricted food intake. The symptoms of pellagra can vary depending on the severity of the deficiency, but the classic signs are often referred to as the "3 Ds":
Dermatologic (Skin) Symptoms:
- Erythema (redness) and dryness of exposed skin
- Scaly, thickened skin (hyperkeratosis)
- Dermatitis and peeling
- Sun sensitivity
- Mouth sores and angular cheilosis (cracked corners of the mouth)
Digestive (Gastrointestinal) Symptoms:
- Diarrhea
- Abdominal pain
- Nausea and vomiting
- Gastritis (inflammation of the stomach lining)
- Stomatitis (inflammation of the mouth)
- Glossitis (inflammation of the tongue)
Neurologic (Nervous System) Symptoms:
- Irritability
- Restlessness
- Confusion
- Anxiety
- Memory loss
- Dementia
- Psychosis
Other Symptoms:
- Fatigue
- Weakness
- Weight loss
- Growth failure (in children)
- Impaired immune function
Advanced Stages:
In severe cases, pellagra can lead to:
- Hallucinations
- Seizures
- Coma
- Death
It's important to note that not all individuals with a niacin deficiency will experience all of these symptoms. The severity and presentation of symptoms can vary depending on the individual's overall health and the duration of the deficiency.
