The word ‘beriberi’ comes from a Sinhalese phrase “I cannot, I cannot” signifying the condition of the body to perform any bodily functions once the neurons are completely damaged or suffering from polyneuritis (i.e. inflammation of the neurons) due to extreme thiamine deficiency.

Diagnosis and Treatment

Beriberi is usually diagnosed by a doctor by performing a series of blood and urine tests and acknowledging the patient's past medical history. A person suffering from thiamine deficiency has a lower concentration of thiamine in the blood and a higher concentration of it in the urine.

The doctor might also perform a thorough physical examination to check for any neurological damage, loss of sensation, loss of coordination, weakened reflexes and inability to walk to straight.

Apart from this, he may also perform a thorough check-up of the heart, breathing rate and any pain and swelling in the hands and feet.

Beriberi can easily be treated by taking thiamine supplements orally or through injections as prescribed by the doctor. If treated on time, beriberi can easily be cured and the underlying health problems can also be treated.

One can also prevent this deficiency by following a well-balanced diet enriched with foods containing vitamin B1 like nuts, seeds, legumes, green veggies, dairy products, whole grains, fish and meat. Also Read: 5 must-have components for a well-balanced diet
