Which symptoms are commonly associated with beriberi?

The symptoms commonly associated with beriberi include polyneuropathy and heart failure, which is characteristic of this deficiency disorder caused by a lack of thiamine (vitamin B1).

Beriberi is categorized mainly into two forms: wet and dry. Wet beriberi typically presents with cardiovascular symptoms, which may include heart failure, edema, and increased heart rate due to fluid retention. Dry beriberi, on the other hand, is more associated with neurological symptoms, particularly polyneuropathy, which involves damage to peripheral nerves, leading to weakness, numbness, and pain in the limbs. Both forms illustrate the range of symptoms resulting from thiamine deficiency.

The other choices, while referencing various symptoms related to different deficiencies or conditions, do not align with the classic presentation of beriberi. For instance, dermatitis and dementia are more closely associated with niacin (vitamin B3) deficiency, while seizures and irritability may indicate a lack of other nutrients like magnesium or other neurological issues. Muscle cramps and fatigue might suggest electrolyte imbalances or other deficiencies but are not specific to beriberi. Understanding these specific associations helps in identifying vitamin deficiencies and their respective clinical manifestations effectively.
