Guide To The Symptoms Of A Thiamine Deficiency

Nausea And Vomiting

Nausea and vomiting is an uncommon symptom manifestation in a thiamine deficiency. The mechanism behind the occurrence of this symptom is similar to what adversely affects the reflexes. A build-up of lactic acid and pyruvic acid in the blood can cause inflammation in the fibers of a nerve the brain uses to communicate with the digestive tract. This nerve is called the vagus nerve, and it is responsible for the stimulation of involuntary movements in the stomach, esophagus, and most of the intestines. These movements help food travel through the gastrointestinal tract. When the vagus nerve becomes inflamed and swollen, it can cause abnormalities in the transmission of signals between the brain and muscles that produce these movements in the stomach and esophagus. When these abnormalities include a spasmodic misfiring of nerve impulses, the esophagus and or stomach can move too much. This abnormal movement can cause the patient to feel nauseated and or vomit as a result of their thiamine deficiency.
