Vomiting and diarrhea are the primary symptoms of gastroenteritis, according to WebMD. Other symptoms include fever, headache, stomach pain and cramping. Vomiting and diarrhea can cause dehydration, which leads to a dry mouth and dry skin.
Gastroenteritis is stomach and intestine inflammation, notes MedicineNet. Bacteria and viruses, such as norovirus and rotavirus, cause this condition. Vomiting is a common symptom that can last for about two to five days. Children with this condition may experience diarrhea and may refuse to eat or drink, leading to weight loss and pinched skin.
Viral gastroenteritis can affect anyone and spreads through contaminated water or food or through close contact with infected people, states Healthline. Children and older people are at higher risk of developing viral gastroenteritis, especially if their immune systems are weak. A person may experience sweating, loss of appetite, abdominal cramps and muscle aches.
Bacterial gastroenteritis, which irritates the intestines and the stomach, mainly occurs due to poor hygiene, explains Healthline. Patients should drink fluids regularly throughout the day and eat little and often, especially foods that are high in potassium, such as fruit juice and bananas. Patients should also wash their hands before handling food or after visiting the toilet, avoid consuming raw meat and unpasteurized milk, and store food at very cold or hot temperatures.
