The disease commonly known as the "3D disease" is pellagra.
What is Pellagra?
Pellagra is a disease caused by a deficiency of niacin (vitamin B3). It's characterized by a specific set of symptoms, often referred to as the "3 Ds":
- Diarrhea: Digestive issues, often leading to loose stools.
- Dermatitis: Skin problems, typically a rash that appears in areas exposed to sunlight.
- Dementia: Cognitive decline, including confusion and memory loss.
The "4th D"
Some healthcare providers also include a fourth "D," which is death. This can occur if pellagra is left untreated for several years.
Key Aspects of Pellagra:
- Cause: Deficiency in niacin (vitamin B3).
- Symptoms: The "3 Ds" – diarrhea, dermatitis, and dementia.
- Severity: Can be fatal if left untreated.
Here is a summary of Pellagra symptoms in a table:
| Symptom | Description |
|---|---|
| Diarrhea | Loose, frequent bowel movements |
| Dermatitis | Rash, often symmetrical and in areas exposed to sunlight, may appear red/dark |
| Dementia | Cognitive decline, confusion, memory loss |
Conclusion
Pellagra is the disease recognized by its classic symptoms of diarrhea, dermatitis, and dementia, often known as the "3D disease," and can be fatal if untreated.
