Beriberi is a potentially life-threatening condition caused by a severe deficiency of thiamine (vitamin B1). It is characterised by impairment of the nerves and heart, and can cause severe and even life-threatening symptoms. The condition is rare in Western countries, where most people consume enough thiamine in their diet, but it is relatively common elsewhere. The leading cause of beriberi is a diet low in thiamine, or a problem that limits the body's ability to process it. Diets that are high in calorie-rich polished rice or cassava root, and low in thiamine-containing animal products or vegetables, can lead to beriberi.

What You'll Learn
Alcoholism and beriberi
Beriberi is a severe and potentially life-threatening condition that occurs due to a deficiency of thiamine (vitamin B1). Thiamine is essential for breaking down and digesting food, maintaining metabolism, and supporting the nervous system and cardiovascular system.
Alcoholism and alcohol abuse are significant risk factors for developing beriberi. Alcohol interferes with the body's ability to absorb and utilise thiamine, leading to a deficiency. Heavy alcohol consumption causes inflammation of the stomach lining and digestive tract, further reducing the absorption of vitamins and contributing to poor nutrition. Alcoholism is often associated with a poor diet and inadequate intake of nutritious foods, which can exacerbate the risk of thiamine deficiency.
The Department of Health & Human Services estimates that 80% of people who abuse alcohol will develop thiamine deficiency. The risk is particularly high in individuals with alcohol use disorder, where alcohol consumption impairs the absorption and utilisation of thiamine, leading to a deficiency. This is a concerning issue, as thiamine deficiency can cause serious health complications, including beriberi.
Alcohol-related beriberi often manifests as dry beriberi, a form of nutritional neuropathy. Dry beriberi damages the central and peripheral nervous systems, leading to decreased muscle strength, impaired reflexes, numbness in the extremities, and in severe cases, muscle paralysis. It can be challenging to diagnose as it may resemble other types of neuropathy, including alcoholic neuropathy. However, early diagnosis and treatment are crucial to prevent the progression of beriberi to Wernicke-Korsakoff syndrome, a serious and potentially irreversible brain injury.
To prevent and treat beriberi in individuals struggling with alcoholism, addressing alcohol consumption is essential. Reducing or quitting alcohol can improve thiamine absorption and utilisation. Additionally, nutritional interventions, including vitamin B1 supplements and a diet rich in thiamine, can help restore thiamine levels. However, it is important to note that diet and supplements alone may not be effective if heavy alcohol use continues, as alcohol blocks the absorption of thiamine.

High-carb diets and beriberi
Beriberi is a severe and potentially life-threatening condition caused by a deficiency of thiamine, or vitamin B1. Thiamine is essential for several bodily functions, including breaking down and digesting food, maintaining metabolism, and supporting the nervous system and cardiovascular system.
A high-carbohydrate diet, particularly one that includes refined carbs, is a risk factor for developing beriberi. Refined carbs, such as white bread, pasta, and rice, have been stripped of their outer layers during processing, which removes essential nutrients like thiamine. As a result, consuming a diet high in refined carbs can lead to a deficiency of this vital vitamin.
During World War II, prisoners of war who relied solely on white rice as a food source often developed beriberi due to the lack of nutrients in refined carbohydrates. Similarly, populations in 19th-century Japan who consumed primarily polished white rice experienced high rates of beriberi. These historical examples illustrate the dangers of a diet heavily reliant on refined carbohydrates.
It is important to note that not all carbohydrates are unhealthy. Many nutrient-dense, high-carb foods can be beneficial and are excellent sources of good-quality carbohydrates. These include whole grains, such as brown rice, quinoa, and oats, as well as pulses, fruits, and vegetables. These unrefined, minimally processed carbohydrate sources often contain a variety of vitamins and minerals in addition to carbohydrates.
To reduce the risk of beriberi, it is recommended to consume a varied and nutritionally balanced diet that includes whole foods and a range of vitamins and minerals. While carbohydrates are an essential component of a healthy diet, it is crucial to prioritise nutrient-dense options and avoid excessive consumption of refined carbs to ensure adequate thiamine intake and overall well-being.

Genetic beriberi
Beriberi is a potentially life-threatening condition that occurs due to a severe deficiency of thiamine (vitamin B1). Thiamine is an essential nutrient that plays a crucial role in various bodily functions, including the breakdown and digestion of food, metabolism, and the proper functioning of muscles and the nervous system.
The condition is often missed or misdiagnosed in non-alcoholics, as beriberi is predominantly associated with alcohol use disorder in developed countries. Alcohol interferes with the body's ability to absorb and store thiamine, making it a more commonly recognised cause of beriberi in these regions. However, it is important to consider genetic beriberi as a potential diagnosis, especially if there is a family history of related conditions.
The treatment for genetic beriberi aims to increase thiamine levels in the body, just as with other forms of beriberi. Doctors may recommend oral supplements, injections, or infusions of thiamine, depending on the patient's overall health and the severity of the deficiency. Early intervention is crucial to prevent irreversible damage to the heart and nervous system.
If left untreated, genetic beriberi can lead to severe complications, including Wernicke-Korsakoff syndrome, a type of encephalopathy characterised by damage to the brain, particularly the thalamus and hypothalamus. This can result in severe confusion, memory loss, and other neuropsychiatric symptoms. Therefore, it is essential to seek medical attention and begin treatment as soon as possible to manage genetic beriberi effectively and prevent long-term health consequences.

Preventing beriberi with diet
Beriberi is a life-threatening condition caused by a severe deficiency of thiamine (vitamin B1). It is very rare in regions with access to vitamin-enriched foods, such as certain breakfast cereals and breads. However, it is relatively common in parts of the world where the diet includes unenriched, processed white rice, which has much less thiamine than brown rice.
To prevent beriberi, it is important to consume enough thiamine-rich foods. Typically, a person who eats a healthy, balanced diet with a focus on whole foods will not need to worry about thiamine deficiency. Foods that naturally contain thiamine include:
- Beans and legumes
- Nuts
- Pork
- Whole grains
- Fortified cereals
- Bread
Breastfeeding mothers need daily thiamine in their diet. If you are breastfeeding, make sure that your diet contains all vitamins. If your infant is not breastfed, ensure that the infant formula contains thiamine and is purchased from a reliable source.
In addition, limiting alcohol consumption helps reduce your risk of developing beriberi. Alcohol use disorder is a common cause of beriberi in developed nations, as alcohol makes it more difficult for the body to process and absorb thiamine.

Beriberi and malnutrition
Beriberi is a severe and potentially life-threatening condition that occurs due to a deficiency of thiamine, also known as vitamin B1. Thiamine is essential for the body to function properly, as it helps break down and digest food, keeps the metabolism going, and supports the muscles and nervous system.
The condition is rare in Western countries, where most people consume enough thiamine in their diet through vitamin-enriched foods such as bread and cereals. However, beriberi is still prevalent in other parts of the world, particularly in regions where the diet includes unenriched, processed white rice, which has a significantly lower amount of thiamine compared to brown rice.
Malnutrition is a significant factor in the development of beriberi. It is particularly relevant in the context of infantile beriberi, which affects babies of malnourished mothers. These mothers may not be getting enough thiamine in their diet, leading to a deficiency that is then passed on to their infants through breast milk or formula. Inadequate thiamine intake during pregnancy can also lead to extreme nausea and vomiting, further contributing to malnutrition and increasing the risk of beriberi for both mother and child.
Additionally, certain medical conditions and lifestyle factors can contribute to malnutrition and increase the risk of beriberi. For example, people with digestive problems, inflammatory bowel disease, or eating disorders may have difficulty absorbing nutrients, including thiamine, from their diet. Alcohol abuse is another significant factor, as excessive alcohol consumption can lead to poor nutrition and interfere with the body's ability to absorb and store thiamine.
The treatment for beriberi focuses on increasing thiamine levels in the body. Doctors may recommend oral supplements, injections, or intravenous thiamine administration, depending on the severity of the case. Early diagnosis and treatment are crucial, as beriberi can lead to irreversible damage to the heart and nervous system if left untreated.
