Vitamin B1 is also called thiamine, plays an important role in the body's metabolism and nerve function. A deficiency in this vitamin can lead to various health problems.
The deficiency of vitamin B1 was first documented in the medical books of ancient China. In 1884, a Japanese physician noticed a high rate of disease and mortality among Japanese sailors who ate only rice for months at sea. When provided a more diversified diet that included entire grains, meats, beans, and vegetables, disease and death rates decreased dramatically. According to Dr Rajiv Chaudhary, MBBS, MD, New Delhi, here are seven signs that you might have a vitamin B1 deficiency:
1. Weakness and Fatigue
“Vitamin B1 is essential for converting carbohydrates into energy. A deficiency can lead to reduced energy production, resulting in feelings of weakness, fatigue, and lethargy, even with adequate rest,” said Dr Chaudhary.

2. Loss of Appetite
“Thiamine deficiency can affect the digestive system, leading to a loss of appetite and decreased food intake. This can further exacerbate the deficiency, creating a vicious cycle of nutrient depletion,” Dr Chaudhary stated.
3. Muscle Weakness and Pain
As per Dr Chaudhary, thiamine is involved in muscle function and nerve signaling. A deficiency can result in muscle weakness, cramps, and pain, particularly in the legs and feet. In severe cases, it may lead to muscle wasting and difficulty walking.
4. Nerve Damage and Tingling Sensations
According to Journal Continuum, thiamine deficiency can damage the peripheral nerves, leading to symptoms such as tingling, numbness, and burning sensations, especially in the hands and feet. This condition is known as peripheral neuropathy.
5. Mental Confusion and Memory Problems
Thiamine plays a crucial role in brain function and cognitive health. A deficiency can lead to mental confusion, difficulty concentrating, memory problems, and even mood changes such as irritability or depression.
6. Digestive Issues
Thiamine deficiency can affect the gastrointestinal tract, leading to symptoms such as constipation, indigestion, and bloating. In severe cases, it may cause a condition known as beriberi, characterised by severe digestive and neurological symptoms.

7. Cardiovascular Problems
Thiamine deficiency can impact the cardiovascular system, leading to symptoms such as rapid heart rate, shortness of breath, and swelling in the lower extremities. In severe cases, it may lead to heart failure or other cardiovascular complications.
If you see any of these signs or symptoms, especially if they persist or worsen over time, you should consult a healthcare professional for a proper diagnosis and treatment. Thiamine deficiency can be detected via blood testing, and supplements or dietary adjustments may be prescribed to correct the deficit and ease symptoms. It's also critical to address any underlying illnesses or lifestyle factors that could lead to vitamin B1 deficiency, such as a poor diet, alcoholism, or certain medical disorders.
