Understanding Gastroenteritis: Causes, Symptoms, and Treatment
Learn about gastroenteritis, its causes, symptoms, prevention tips, and effective treatments for quick digestive recovery.
Gastroenteritis
Gastroenteritis, commonly known as stomach flu, is an inflammation of the stomach and intestines caused by infections, toxins, or irritants. It leads to symptoms such as vomiting, diarrhea, abdominal pain, and dehydration. While most cases are short-term, severe or untreated infections can cause serious complications—especially in children, older adults, and immunocompromised individuals.
At VS Hospitals, the Gastroenterology Department offers advanced diagnostic and treatment solutions for all forms of gastroenteritis—bacterial, viral, or parasitic. The hospital focuses on quick symptom control, hydration therapy, and infection management to ensure patients recover safely and completely.

Gastroenteritis – Risk Factors
Smoking
Smoking is one of the leading causes of bladder cancer. Chemicals in tobacco smoke can damage the lining of the bladder, increasing the risk.
Gender
Men are at a higher risk of developing bladder cancer than women.
Chronic Bladder Infections or Inflammation
Conditions such as bladder infections and long-term bladder inflammation can increase the risk.
Exposure to Chemicals
Prolonged exposure to certain chemicals, especially those used in the dye industry, rubber production, and chemical manufacturing, increases the risk.
Contaminated food or water
Poor hygiene or unsafe water sources are the leading causes of infection.
Close contact with infected individuals
The illness spreads easily in crowded environments or households.
Weakened immune system
People with chronic illnesses or those undergoing chemotherapy are more prone.
Poor sanitation
Improper handwashing or unclean kitchen environments promote bacterial growth.
Travel exposure
Visiting regions with inadequate sanitation can expose individuals to new infectious strains.
Food habits
Consuming raw seafood, undercooked meat, or street food can trigger infection.
Seasonal factors
Viral gastroenteritis, especially from rotavirus or norovirus, spikes during winter months.

Diet plays a crucial role in both managing and recovering from gastroenteritis. Proper nutrition helps restore strength, balance electrolytes, and prevent recurrence.
- Hydration is Key: Drink plenty of fluids like water, clear soups, coconut water, and electrolyte solutions.
- Oral Rehydration Solution (ORS): Helps replace lost salts and fluids.
- Soft, Bland Foods: Eat easily digestible foods like rice, bananas, boiled potatoes, applesauce, and toast (BRAT diet).
- Avoid Dairy Products: Milk and cheese can worsen diarrhea during infection.
- Limit Fatty and Spicy Foods: These irritate the stomach lining and increase discomfort.
- Avoid Caffeine and Alcohol: Both contribute to dehydration and delay recovery.
- Small, Frequent Meals: Promote digestion without overburdening the stomach.
- Probiotics: Yogurt and probiotic drinks help restore healthy gut bacteria.
- Boiled or Filtered Water: Prevents further bacterial contamination during recovery.
- Vitamin-Rich Foods: Include soft fruits and vegetables once digestion stabilizes.
