Biotin deficiency occurs when the body is unable to absorb the necessary amount of biotin required for its optimal functioning. This can happen due to various reasons, including inadequate dietary intake, certain medical conditions affecting absorption, prolonged use of certain medications, or genetic factors that hinder the body's ability to process biotin.
The symptoms of biotin deficiency can vary widely and may include hair loss or thinning, a scaly red rash around the eyes, nose, mouth, and genital area, brittle nails, fatigue, and neurological symptoms like depression, lethargy, hallucinations, and numbness or tingling in the extremities.
