Thiamine deficiency is a condition caused by a lack of thiamine (vitamin B1) in the body. It can lead to a variety of symptoms, including fatigue, confusion, irritability, muscle weakness, and digestive problems. Severe thiamine deficiency can cause a condition called beriberi, which can lead to heart failure, nerve damage, and even death. Thiamine deficiency is most commonly caused by a poor diet, alcoholism, or certain medical conditions. Treatment typically involves taking thiamine supplements and eating a balanced diet.
