People with alcohol dependence In highly industrialized countries, chronic alcohol use disorders appear to be the most common cause of thiamin deficiency [1].
Vitamin B-1 (thiamine) plays a huge part in your baby's brain development. Pregnant women need about 1.4 milligrams of vitamin B-1 daily. Natural sources of vitamin B-1 are found in: whole grain pastas.
Risk Factors for Thiamine Deficiency
Alcoholism. Gastric bypass surgery. Genetic beriberi (inability to absorb thiamine)
Beriberi is a disease caused by a vitamin B1 deficiency, also known as thiamine deficiency. It often occurs in developing countries among people with a diet that consists mostly of white rice or highly refined carbohydrates. There are two types of the disease: wet beriberi.
With prolonged thiamine deficiency, patients may endorse loss of sensation in the extremities, symptoms of heart failure including swelling of the hands or feet, chest pain related to demand ischemia, or feelings of vertigo, double vision, and memory loss.
Thiamine deficiency contributes to a number of conditions spanning from mild neurological and psychiatric symptoms (confusion, reduced memory, and sleep disturbances) to severe encephalopathy, ataxia, congestive heart failure, muscle atrophy, and even death.
Using this type of clinical thiamine deficiency correction, some heart-related symptoms can be reversed within hours to days ( 2 ). It may take 3 to 6 months to reverse brain and nervous system effects, and people with severe neuropathy due to a delay in diagnosis or treatment may have permanent damage ( 2 ).
Man-made thiamine can be used to treat or prevent vitamin B1 deficiency (this is when you do not have enough of this vitamin in your body). It is sometimes also used to treat to children with rare conditions like maple syrup urine disease and congenital lactic acidosis.
Early signs of thiamine deficiency include peripheral neuropathies in adults and adolescents and fussiness and irritability in infants. Weakness, nystagmus, ophthalmoplegia, ataxia, and cognitive impairment accompany progression of the disease. Infants may be noted to have a lack of tone.
Because beriberi impairs reflexes and motor function, it can eventually lead to deadly fluid build-up in the heart and lower limbs. Another result of serious thiamin deficiency often seen with alcohol abuse is Wernicke-Korsakoff syndrome that may cause confusion, loss of muscle coordination, and peripheral neuropathy.
Thiamine deficiency is a medical condition of low levels of thiamine (Vitamin B1). A severe and chronic form is known as beriberi. The two main types in adults are wet beriberi and dry beriberi. Wet beriberi affects the cardiovascular system, resulting in a fast heart rate, shortness of breath, and leg swelling.
Thiamine is generally safe. Very high doses may cause stomach upset. Taking any one of the B vitamins for a long period of time can result in an imbalance of other important B vitamins.
Early symptoms of thiamin deficiency are vague. They include fatigue, irritability, poor memory, loss of appetite, sleep disturbances, abdominal discomfort, and weight loss. Eventually, a severe thiamin deficiency (beriberi) may develop, characterized by nerve, heart, and brain abnormalities.
what is a vitamin b1 thiamine? A vitamin B1 test is a blood test to identify if there is a deficiency in the vitamin which can lead to Beri Beri and other illnesses.
In conjunction with whole blood or erythrocyte transketolase activity preloading and postloading, a thiamine loading test is the best indicator of thiamine deficiency. An increase of more than 15% in enzyme activity is a definitive marker of deficiency.
Additionally, certain food products such as tea, coffee, raw fish, and shellfish contain thiaminases - enzymes that destroy thiamine. Thiamine deficiency can affect the cardiovascular, nervous, and immune systems, as commonly seen in wet beriberi, dry beriberi, or Wernicke-Korsakoff syndrome.
Vitamins B1 and B2 not only turn food into energy, but also produce melatonin, the sleep hormone. The production of melatonin shows that these vitamins encourage sleep. Taking a thiamine (vitamin B1) supplement can help you sleep better throughout the night, which will allow you to wake up feeling refreshed.
Alcohol decreases the absorption of dietary thiamine by at least 50 percent and can damage the lining of the intestinal tract, resulting in more malabsorption. Cut out caffeine. Coffee and tea, although less damaging to the intestinal tract, can wreak havoc on thiamine absorption.

A deficiency of a single vitamin, B1 (thiamine), can cause a potentially fatal brain disorder called Wernicke encephalopathy. Symptoms can include confusion, hallucinations, loss of muscle coordination and vision problems. Untreated, the condition can lead to irreversible brain damage and death.
There are high concentrations of Vitamin B1 in the outer layers and germ of cereals, as well as in yeast, beef, pork, nuts, whole grains, and pulses. Fruit and vegetables that contain it include cauliflower, oranges, potatoes, asparagus, and kale.
As thiamine deficiency progresses, extreme loss of muscle mass can be observed. Early reports of the phenomenon particularly indicate severe wasting of the gastrocnemii. Adults demonstrate considerable weakness related to muscle loss and peripheral neuropathy.
The biologically active form of the vitamin, thiamine pyrophosphate (TPP), is best measured in whole blood and is not found in measurable concentration in plasma. Plasma thiamine concentration reflects recent intake rather than body stores; therefore, whole blood is the preferred specimen for thiamine assessment.
Studies show that high blood sugar and insulin levels improve after taking vitamin B1 for 6 weeks. B1 also helps reduce high blood pressure and heart complications in people with diabetes.
Oral forms of thiamine have not been associated with adverse events, ALT elevations or liver injury even when given in high doses. Parenteral administration of thiamine can be associated with immediate hypersensitivity reactions including anaphylaxis, but these are rare (<1:1000).
