What deficiency disease is caused by a lack of vitamin B1 in the diet?

The deficiency disease caused by a lack of vitamin B1, also known as thiamine, is Beri-beri. This condition affects the nervous system and cardiovascular health, leading to symptoms such as weakness, pain, and in severe cases, heart problems and nerve damage. Thiamine plays a crucial role in carbohydrate metabolism and energy production, and without adequate amounts in the diet, the body's ability to generate energy is impaired.

In contrast, Pellagra is associated with a deficiency in niacin (vitamin B3), resulting in symptoms like diarrhea, dermatitis, and dementia. Scurvy is caused by a lack of vitamin C, leading to symptoms such as fatigue, swollen gums, and joint pain. Rickets is related to deficiencies in vitamin D, calcium, or phosphate, causing bone weakness and deformities, particularly in growing children. Recognizing which deficiency leads to which disease helps highlight the importance of maintaining a balanced diet rich in essential vitamins.
