Beriberi is a condition that arises due to a deficiency of thiamine, also known as vitamin B1. This essential nutrient plays a crucial role in the body’s metabolism, particularly in converting carbohydrates into energy. The absence of sufficient thiamine can lead to various health complications, collectively termed as beriberi.

Beriberi manifests in different forms, primarily affecting the cardiovascular, nervous, and muscular systems. Historically, it has been prevalent in populations where polished rice is a dietary staple, as the refining process removes thiamine from the grain.

Types of Beriberi

There are three main types of beriberi: Wet beriberi, Dry beriberi and Infantile beriberi.

Wet Beriberi

Primarily affects the cardiovascular system, leading to symptoms such as gradually swelling of the lower extremities, increased heart rate, and shortness of breath. Ultimately involving the whole body with ascites and plueral effusion. Due to lack of this Vitamin carbohydrate metabolism is disturbed. So lactic acid and pyruvic acids acids accumulate in the body which result in vasodilation oedema. General symptoms include weakness, malaise, palpitation, oedema.

Dry Beriberi

On the other hand, predominantly impacts the nervous system, resulting in nerve degeneration,neurological symptoms like muscle weakness, tingling sensations, numbness instocking and gloves area on both sides along with cramps.

Infantile Beriberi

Infantile beriberi is a severe thiamine deficiency that affects infants, typically due to inadequate thiamine intake from breastfeeding mothers with thiamine deficiency. It can lead to symptoms such as mother notices that the child is restlessness and crying all the time. Breathlessness and cyanosis are present. Due to cardiac enlargement and failure. This condition is rapidly fatal. Severe form of Beriberi heart disease may develop along with metabolic acidosis and this is called Shoshin Beriberi in the orient.

Causes of Beriberi

  • Beriberi typically occurs due to inadequate intake of thiamine-rich foods or conditions that impair thiamine absorption or utilization within the body.
  • Chronic alcoholism there is poor dietary intake of B1, poor absorption, metabolism and storage.
  • In those who consume only polished rice, Beriberi is seen,Certain gastrointestinal disorders, and extreme diets are among the factors that can contribute to thiamine deficiency.
  • In chronic malabsorption, protien calorie malnutrition, chronic Dialysis or long standing Glucose infusion B1 deficiency also results.

Symptoms of Beriberi

The symptoms of beriberi can vary depending on the type and severity of the deficiency. Common signs include fatigue, irritability, muscle cramps, difficulty concentrating, and swelling in the legs. In severe cases, beriberi can lead to heart failure, paralysis, or even death if left untreated.

Diagnosis of Beriberi

Diagnosing Beriberi

Diagnosing beriberi typically involves a thorough medical history review, physical examination, and laboratory tests to assess thiamine levels in the blood. Imaging studies such as echocardiography may be performed to evaluate cardiac function in individuals suspected of having wet beriberi.

Prevention of Beriberi

Dietary Changes

Preventing beriberi involves consuming a balanced diet rich in thiamine-containing foods such as whole grains, legumes, nuts, seeds, lean meats, and fortified cereals. Avoiding excessive consumption of refined carbohydrates, particularly polished rice, can also help prevent thiamine deficiency.


In populations at risk of thiamine deficiency, such as pregnant women, breastfeeding mothers, and individuals with chronic medical conditions, thiamine supplementation may be recommended to ensure adequate intake.

Lifestyle Modifications

Maintaining a healthy lifestyle that includes regular physical activity, moderate alcohol consumption, and avoidance of fad diets can also contribute to preventing thiamine deficiency and reducing the risk of beriberi.

Current Perspectives on Beriberi

Despite significant advancements in nutrition science and public health, beriberi remains a concern in certain populations, particularly in developing countries where access to nutritious foods may be limited. Efforts to address thiamine deficiency through food fortification programs and public health interventions have shown promising results but require continued attention and investment.

Research and Advancements in Beriberi Management

Ongoing research aims to improve our understanding of thiamine metabolism, identify novel biomarkers for thiamine deficiency, and develop targeted interventions for individuals at risk of beriberi. Clinical trials investigating the efficacy of high-dose thiamine therapy in various patient populations are also underway, with the potential to revolutionize beriberi management.

FAQs about Beriberi Deficiency

Can beriberi be cured completely?

While beriberi can be effectively treated with thiamine supplementation and dietary changes, the extent of recovery depends on the severity of the deficiency and the presence of any underlying medical conditions.

Is beriberi common in developed countries?

Beriberi is relatively rare in developed countries due to widespread access to diverse and fortified foods. However, certain populations, such as individuals with alcohol use disorder or gastrointestinal disorders, may still be at risk.

Are there any side effects of thiamine supplementation?

Thiamine supplementation is generally safe when taken as directed. However, in rare cases, high doses of thiamine may cause allergic reactions or gastrointestinal disturbances.

How long does it take to recover from beriberi?

The recovery time for beriberi varies depending on factors such as the severity of the deficiency, the individual


Beriberi deficiency, resulting from inadequate intake or absorption of thiamine, continues to pose a significant health threat globally, particularly in vulnerable populations. Recognizing the diverse clinical manifestations of beriberi, implementing targeted prevention strategies, and promoting thiamine supplementation are crucial steps in mitigating the burden of this preventable condition and improving overall public health.
