Vitamin B1 – Thiamine

Thiamine: the forgotten hero for your nervous system and health.

In a world where health and nutrition are on everyone's lips, it's easy to forget the simple but important role of certain tiny vitamins.

Thiamine (vitamin B1) is one such vitamin that deserves more attention. This water-soluble vitamin plays an indispensable role in the body's energy metabolism, especially in relation to the brain and nervous system.

What happens when we don't get enough thiamine?

And how can a deficiency of this vitamin be the cause of serious diseases, which may never be linked to thiamine deficiency? Maybe it's even just ligner on other diseases, when we start to lack this vitamin?

The role of thiamine in the body

Thiamine acts as a coenzyme, simply put, a helps, in several important enzymatic processes that are essential for the body's energy production. Without sufficient thiamine, we cannot convert the food we eat into energy efficiently. This affects our vitality levels og cognitive functions. In other words, that health is bubbling, and the brain flourishes, and arms and legs shine as they should.

But thiamine is much more than that. The vitamin is necessary for the nervous system to function optimally, by supporting nerve signals, protecting nerve cells and helping with the synthesis of neurotransmitters – so the production of communication materials, which means that your nerve impulses fly where they need to, and exactly where they need to go, and communicate what they need to.

Thiamine also plays a protective role against oxidative damage and is important for normal muscle and heart function.

What happens when you lack thiamine?

Thiamine deficiency can lead to serious health problems, especially related to the nervous system. The most well-known diseases related to thiamine deficiency include:

1. Beriberi

Beriberi is a classic disease that occurs due to long-term thiamine deficiency. There are two main forms:

• Wet beriberi affects the cardiovascular system and can lead to swelling, which in the literature is called edema – fluid accumulation in the tissues, but more seriously shortness of breath, and later heart failure.
• Dry beriberi affects the nervous system and leads to muscle weakness, paralysis, and severe numbness and pain in the arms and legs.

It is rare to have both at the same time, but it can certainly occur with severe malnutrition, such as bulimia, anorexia, alcoholism, etc. These all have malnutrition as a common denominator, and are worth looking into.

Other causes of malnutrition, in this case thiamine B1, can include gastrointestinal disorders (such as Crohn's disease or celiac disease), which inhibit nutrient absorption, as well as chronic diseases such as cancer, HIV/AIDS, or tuberculosis, which can increase the body's need for nutrients or reduce food intake.

Economic factors such as poverty or food insecurity can also lead to a lack of adequate, nutritious food.

Certain medications or treatments (such as chemotherapy) can also affect appetite or nutrient absorption.

2. Wernicke-Korsakoff syndrome

Wernicke-Korsakoff syndrome is a serious neurological condition that can occur due to thiamine deficiency, especially in people suffering from alcoholism. The syndrome consists of two main phases:

• Wernicke's encephalopathy, which is an acute phase characterized by brain failure, confusion, nystagmus (uncontrolled eye movements), and ataxia (coordination problems).
• Korsakoff syndrome, which often follows untreated Wernicke's encephalopathy and can lead to memory loss, disorientation, and personality changes.

3. Peripheral neuropathy

One of the first signs of thiamine deficiency may be: peripheral neuropathy, which involves numbness, tingling, and pain in the hands and feet. This can easily be mistaken for diabetes-related neuropathy or other neurological conditions. If left untreated, neuropathy can progress to paralysis and permanent damage to the nervous system.

4. Carpal tunnel syndrome

Interestingly enough, Carpal Tunnel Syndrome, which involves pain and numbness in the hand, can also be the result of neuropathy caused by thiamine deficiency. Thiamine is important for nerve function in the hand, and a deficiency can lead to pressure on the median nerve in the wrist, which can cause symptoms similar to carpal tunnel syndrome.

Is thiamine deficiency more dramatic than other deficiencies?

Thiamine deficiency is a relatively rapidly developing condition, and the consequences can be dramatic if not treated promptly. This deficiency tends to affect the nervous system particularly severely, and symptoms such as neuropathy or confusion can develop in a short time.

This makes thiamine deficiency a disease that can be far more dramatic than many other vitamin deficiencies, such as vitamin D or iron deficiency. If the deficiency is not treated in time, it can lead to permanent brain damage and neurological defects.

In cases like Wernicke-Korsakoff syndrome, treatment is essential to prevent irreversible damage. The sooner treatment is started, the greater the chance of reversing or reducing the effects of the disease.

Is thiamine deficiency reversible?

The good news is that thiamine deficiency can be reversed, especially if detected early. Thiamine can be administered through supplements or intravenous infusion, and in many cases, neurological symptoms will improve significantly. Even in cases such as Wernicke-Korsakoff syndrome, early treatment can lead to improvements in cognition and coordination. However, the longer the deficiency has been present, the greater the risk of permanent damage to the brain and nervous system.

Thiamine's connection with other neurological conditions

Interestingly, there are also several other neurological conditions that can be caused by or worsened by thiamine deficiency. For example, symptoms of peripheral neuropathy og Carpal Tunnel Syndrome in some cases, be a direct result of thiamine deficiency. These conditions can easily be misinterpreted as other, more well-known diseases, making early diagnosis and treatment even more important.

In addition, thiamine deficiency can also worsen or contribute to the development of other neurological diseases, such as: multiple sclerosis (MS) or Parkinson's disease, by affecting the health and function of the nervous system. Although these diseases have other primary causes, a thiamine deficiency can worsen symptoms and make treatment more challenging.

Typical causes of thiamine deficiency

Thiamine deficiency is relatively rare in Western diets, but there are several situations where people may be at risk for deficiency. The most common causes of thiamine deficiency include:

1. Alcoholism

Alcohol abuse is a leading cause of thiamine deficiency. Alcohol inhibits thiamine absorption in the intestine and can lead to reduced storage and utilization of the vitamin in the body. Long-term alcohol use can also lead to poor diet, which exacerbates the deficiency.

2. Poor diet

A monotonous diet with low intake of thiamine-rich foods such as lean meat, fish, and whole grains can lead to deficiency. This is especially common in populations that live on refined carbohydrates, such as white bread and rice, without adequate access to nutritious foods.

3. Malabsorption diseases

Conditions that affect the intestines and hinder the body's ability to absorb nutrients, such as celiac disease, Crohn's diseaseor low acid production in the stomach, can cause the body to not get enough thiamine.

4. Increased need

Particular life stages, such as pregnancy, breastfeeding, or intense physical activity, may increase the need for thiamine. Untreated deficiencies can develop rapidly if the need is not met.

5. Certain medications

Some medications, especially diuretics, can cause the loss of water-soluble vitamins such as thiamine, thus increasing the risk of deficiency.

What about a carnivore diet? A ketogenic diet?

For a ketogenic diet with sufficient meat, fish, eggs, and dairy products, the risk of thiamine deficiency is minimal, as these foods are good sources of the vitamin. The warning about deficiency primarily applies to vegans following a ketogenic diet, as they do not consume thiamine-rich animal products. To avoid thiamine deficiency, it is important to include adequate amounts of these foods in a ketogenic diet.

Food Sources of Thiamine: What Should You Eat?

To avoid thiamine deficiency, it is important to include foods rich in thiamine in your diet. Thiamine is found mainly in animal products, such as:

• Pork (especially fat and ham)
• Lever (especially cattle and pigs)
• Fish (such as salmon, tuna and cod)
• Egg
• Milk and dairy products (like cheese and milk)
• Poultry (like chicken and turkey)

Plant sources such as whole grains, beansand nuts also contain thiamine, but they are not as readily available to the body as animal sources. By including a variety of foods from these sources, you can ensure adequate thiamine intake.

Thiamine – a key to the well-being of the body and brain

Thiamine is an essential vitamin that plays a central role in nervous system health, energy production, and protection against degenerative processes. Thiamine deficiency can lead to a number of serious neurological diseases, such as beriberi, Wernicke-Korsakoff syndrome, peripheral neuropathy, and even Carpal Tunnel Syndrome.

By understanding the importance of thiamine and how a deficiency in this vitamin can lead to serious illnesses, we can better protect ourselves from the potentially dramatic consequences of a condition that can easily be overlooked. Fortunately, thiamine deficiency is reversible if detected early, and by ensuring you get adequate thiamine through a balanced diet, you can maintain a healthy nervous system and good brain health.

Is the understanding of thiamine in development?

1. Thiamine deficiency in wildlife

Recent studies have revealed that thiamine deficiency not only affects humans but also wildlife in a significant way. Researchers have observed that arctic foxes in Norway have had problems with reproduction, and one of the reasons may be a lack of thiamine in their diet. Thiamine deficiency in foxes can lead to reduced appetite, poor coordination, and paralysis of the neck muscles, which affects their ability to hunt and survive.

In Sweden, researchers have also discovered that seabird populations are suffering from thiamine deficiency, leading to paralysis and high mortality among the birds. Symptoms of thiamine deficiency in seabirds include paralysis and abnormal behavior, and treatment trials with thiamine injections have proven effective.

2. Baltic cod and thiamine deficiency

Another study has shown that cod in the Baltic Sea suffer from a severe thiamine deficiency. Researchers have found that a lack of thiamine in the cod's vital organs, such as the liver and brain, leads to growth problems, balance problems, increased mortality, infectious diseases and infestations by parasites. This thiamine deficiency has been present since the late 1990s, and the researchers are calling for further studies to better understand the causes.

3. Thiamine deficiency in patients with alcohol withdrawal

Wernicke's encephalopathy is a serious neurological condition caused by thiamine deficiency, often seen in people with alcoholism. One study examined the incidence of Wernicke's encephalopathy in patients with alcohol withdrawal symptoms and found that the condition is relatively common among this group. Early diagnosis and treatment with thiamine are crucial to prevent permanent brain damage.

4. Thiamine treatment in clinical practice

Thiamine treatment is essential for patients with thiamine deficiency, especially those suffering from Wernicke's encephalopathy or beriberi. An article in the Journal of the Norwegian Medical Association emphasizes the importance of being aware of symptoms of thiamine deficiency and starting treatment early to avoid serious complications.

5. Thiamine and chronic fatigue

A new study has examined the link between thiamine deficiency and chronic fatigue. The research suggests that thiamine supplementation may have a positive effect on people suffering from chronic fatigue, although further studies are needed to confirm these findings.

Conclusion

Recent research has expanded our understanding of thiamine deficiency and its effects on both humans and animals. It is important to be aware of the various symptoms of thiamine deficiency and to seek medical attention if a deficiency is suspected. Early diagnosis and treatment are essential to prevent serious health complications.
