Why typhoid fever have coated tongue?

Pathophysiology of coated tongue in typhoid fever

Typhoid fever is a systemic infection caused by the bacterium *Salmonella enterica* serovar Typhimurium. The bacteria can invade and multiply in the lymphoid tissue of the small intestine, leading to inflammation and ulceration. This can cause a variety of symptoms, including fever, abdominal pain, diarrhea, and vomiting.

In some cases, typhoid fever can also cause a coated tongue. This is thought to be due to a combination of factors, including:

* Toxins: The bacteria that cause typhoid fever produce toxins that can damage the cells of the tongue, leading to inflammation and a white or yellow coating.

* Dehydration: Typhoid fever can cause dehydration, which can lead to a dry mouth and a coated tongue.

* Poor oral hygiene: Typhoid fever can make it difficult to maintain good oral hygiene, which can also contribute to a coated tongue.

Treatment

The treatment for typhoid fever typically involves antibiotics and supportive care. Antibiotics are used to kill the bacteria that cause the infection. Supportive care may include fluids, electrolytes, and pain relievers.

In most cases, a coated tongue will resolve as the underlying infection is treated. However, if the coated tongue is severe or does not improve with treatment, it may be necessary to see a doctor for further evaluation.
