What is Stomach Flu? 

Gastroenteritis is another name for this Stomach Flu. It is frequently brought on by eating food that has been infected with microbiological organisms such as bacteria, viruses, or parasites.

These germs enter the human digestive tract and cause inflammation and irritation of the stomach and intestine linings.

Stomach pains, stomach cramps, nausea, vomiting, diarrhoea, fever, inflammation of lymph nodes, headache, and dehydration are all symptoms of stomach flu.

Dehydration can be life-threatening in various situations. E.coli, salmonella, shigella, and campylobacter are the most prevalent bacteria that cause stomach flu.

Norovirus, rotavirus, and calicivirus are among the viruses that cause stomach flu. 

Lack of cleanliness is the leading cause of stomach flu. Stomach infections are commonly caused by preparing food in unclean vessels, eating unsanitary food, not covering food, not cleaning hands before cooking or eating,

not drinking clean water, and not washing hands properly after changing soiled diapers, among other things. It is a very contagious disease that can be transferred by touching unwashed hands.

People who eat roadside food, pregnant women, newborns, undernourished youngsters, immunocompromised individuals, and the elderly are all at risk. 

In most cases, the illness is self-limiting. To prevent dehydration, the person is encouraged to drink enough fluids. Antibiotics are also prescribed to him to help him battle the infection.

In the most serious cases, medical help is essential. Blood in the stools or vomiting, severe dehydration (dry lips, wrinkled skin, inability to pass urine), high-grade grade fever (≥ 101 ° F),

stomach inflammation, pain in the right bottom area of the stomach, or vomiting that lasts longer than 48 hours all require emergency medical attention.
