Definition

Thiamin deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones., also known as VitaminVitamins are organic compounds that are necessary in small amounts for the normal growth, development, and physiological function of the body. Vitamins must mostly be obtained through food, as the body cannot produce them or not in sufficient quantities. B1 deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones., is a nutritional disease in cats caused by insufficient amounts of thiamin in the body, which can lead to neurological and cardiovascular disorders.

The most important facts at a glance

Thiamin, also known as VitaminVitamins are organic compounds that are necessary in small amounts for the normal growth, development, and physiological function of the body. Vitamins must mostly be obtained through food, as the body cannot produce them or not in sufficient quantities. B1, is crucial for the energy balance of cats, especially for the brain and heart. Since cats rely on animal sources, they obtain thiamin mainly from meat and fish. A deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones. can be caused by cooking food, which destroys thiamin, as well as by consuming raw fish, which contains thiaminase. Unbalanced diets or health problems that interfere with nutrient absorptionAbsorption refers to the uptake of substances by living cells or tissues. In the context of veterinary medicine, it often refers to the absorption of nutrients, drugs, or toxins from the digestive tract into the bloodstream. can also lead to a deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones..

Causes

Thiamin, also known as Vitamin B1, is a water-soluble vitaminVitamins are organic compounds that are necessary in small amounts for the normal growth, development, and physiological function of the body. Vitamins must mostly be obtained through food, as the body cannot produce them or not in sufficient quantities. that plays a crucial role in carbohydrate metabolism. It is necessary for the conversion of carbohydrates into energy by acting as a coenzyme in the enzymaticEnzymatic refers to processes catalyzed by enzymes. Enzymes are proteins that accelerate chemical reactions in the body and are essential for metabolism and numerous other vital functions. processes of energy production. Without sufficient amounts of thiamin, cells cannot produce energy efficiently, which particularly affects tissues such as the brain and heart that rely on a continuous supply of energy.

Since cats are obligate carnivores, they obtain thiamin mainly from animal sources. Fish and meat are particularly rich in this vitaminVitamins are organic compounds that are necessary in small amounts for the normal growth, development, and physiological function of the body. Vitamins must mostly be obtained through food, as the body cannot produce them or not in sufficient quantities.. However, the heat sensitivity of thiamin means that it can be destroyed during food preparation, especially at high temperatures. Furthermore, some raw fish species contain thiaminase, an enzyme that breaks down thiamin. Cats that are regularly fed raw fish have an increased risk of thiamin deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones..

Another cause of thiamin deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones. can be an unbalanced diet. Cats that are fed homemade or unbalanced commercial diets that are not properly formulated to meet all of their nutritional needs may also suffer from a deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones.. GastrointestinalGastrointestinal refers to the gastrointestinal tract, a system that extends from the oral cavity to the anus and is responsible for the digestion of food and the absorption of nutrients. diseases that interfere with nutrient absorptionAbsorption refers to the uptake of substances by living cells or tissues.
