Gastroenteritis Treatment in Delhi, India

Gastroenteritis is a common condition that affects the gastrointestinal tract, causing inflammation of the stomach and intestines. It is often referred to as the stomach flu or food poisoning. Typically caused by a viral or bacterial infection, Gastroenteritis can also be triggered by consuming contaminated food or water. Common symptoms include diarrhoea, vomiting, abdominal pain, and nausea. These symptoms can range from mild to severe and can last anywhere from a few days to a week.

Managing gastroenteritis requires prompt attention and proper care. One needs to stay hydrated, take adequate rest, follow a bland diet, and practise good hygiene.

While most cases of gastroenteritis resolve on their own with proper self-care, seek medical attention if symptoms worsen or persist for an extended period. Infants, young children, older adults, and individuals with weakened immune systems are at a higher risk of complications. Read on to know all about gastroenteritis and how to stay safe.

Gastroenteritis Symptoms

• Diarrhoea: One of the hallmark symptoms of gastroenteritis is frequent loose or watery stools. This can occur suddenly and may be accompanied by an urgent need to use the bathroom.

• Nausea and vomiting: Gastroenteritis can cause feelings of nausea and may lead to vomiting. This can be quite uncomfortable and may contribute to dehydration.

• Abdominal cramps: Many individuals with gastroenteritis experience abdominal cramps and pain. These symptoms can vary in intensity and may come and go throughout the illness.

• Fever and headache: Gastroenteritis can sometimes be accompanied by a low-grade or high-grade fever. Headaches are also common during this time.

• Muscle aches or weakness: Some individuals may experience muscle aches or weakness. This can make it challenging to carry out daily activities.

• Dehydration: Loss of fluids due to diarrhoea, vomiting, and reduced fluid intake can lead to dehydration. Symptoms of dehydration include a dry mouth, excessive thirst, and reduced urine output.

Gastroenteritis Causes

• Viral Infections: Norovirus, Rotavirus, and Adenovirus can cause gastroenteritis. Among these, Norovirus is the leading cause of gastroenteritis worldwide and is responsible for approximately 50% of all cases. Rotavirus primarily affects infants and young children, causing severe diarrhoea and vomiting. Adenovirus can cause gastrointestinal symptoms along with respiratory infections.

• Bacterial Infections: Escherichia coli (E. coli) is a common cause of foodborne gastroenteritis and can be present in undercooked meats or contaminated vegetables. Salmonella is found in contaminated food and water sources, such as raw eggs, poultry, and dairy products. Also, Campylobacter infection usually occurs due to consumption of undercooked chicken or contaminated water.

• Parasitic Infections: Giardia lamblia and Cryptosporidium parvum are two common parasites that can cause gastroenteritis. These are typically found in contaminated water sources, including swimming pools, lakes, and rivers.

• Contaminated food or water sources: Consuming contaminated food or water is one of the primary ways people contract gastroenteritis. Poorly handled or undercooked food increases the risk of bacterial or parasitic infections.

• Poor hygiene practices: Close contact with infected individuals, touching contaminated surfaces and poor hand hygiene, especially after using the bathroom or changing diapers, can contribute to the spread of the infection.

Gastroenteritis Diagnosis

In order to diagnose gastroenteritis accurately, doctors follow a series of steps which are elaborated below.

Medical History and Physical Examination

Doctors begin by taking a detailed medical history, which includes asking about symptoms, recent travel, and any potential exposure to contaminated food or water. A thorough physical examination is then conducted, where the doctor checks for signs of dehydration or tenderness in the abdomen.

Stool Sample Analysis to Detect Pathogens

To confirm the diagnosis, a stool sample is collected and sent for analysis in a laboratory. This helps identify the pathogens responsible for causing gastroenteritis, such as bacteria, viruses, or parasites. These tests can include culture studies, enzyme immunoassays, or polymerase chain reaction (PCR) testing.

Blood Tests to Check for Signs of Dehydration or Infection

Blood tests help determine if there are signs of dehydration or infection in the body. It can provide valuable information about electrolyte levels, liver function, and white blood cell count. All of these can indicate the severity of the illness and guide treatment for gastroenteritis.

Imaging Tests Such as Abdominal X-Rays or CT Scans

In severe cases of gastroenteritis or when complications are suspected, imaging tests like abdominal X-rays or CT scans help evaluate the extent of inflammation or identify any abnormalities in the digestive system. They can help detect complications such as intestinal obstruction, perforation, or inflammation.

Gastroenteritis Treatment

Most cases resolve on their own within a few days with proper treatment for gastroenteritis and care. Some treatment options include

Fluid and Electrolyte Replacement

Frequent vomiting and diarrhoea, causes the body to lose fluids and electrolytes rapidly. To counteract this, oral rehydration solutions (ORS) are used to replenish the body's fluids and electrolytes. Alternatively, in severe cases, intravenous fluids may be necessary.

Dietary Changes

To support a recovering digestive system, doctors may recommend avoiding spicy, fatty, or dairy-rich items, as these can worsen symptoms and irritate the gastrointestinal tract. Consuming easily digestible foods such as plain rice, bananas, toast, boiled potatoes, and clear broths maybe recommended.

Medications

Medications may be necessary to manage specific symptoms of gastroenteritis. Antiemetics can help control nausea and vomiting, antidiarrheal medications can help reduce the frequency of bowel movements, and antibiotics may be prescribed in cases of a bacterial infection.

Rest and Adequate Fluid Intake

Allowing the body to rest, gives it the time and energy to heal. In addition to rest, consume an adequate amount of fluids to prevent dehydration. Sip on water, herbal teas, and broths throughout the day, aiming for at least eight cups of fluid.

Remember, if symptoms worsen or persist beyond a few days, seek medical attention. A doctor will be able to assess the condition and provide appropriate treatment for gastroenteritis.

Types of Gastroenteritis

Gastroenteritis is a common gastrointestinal infection that can be caused by various types of pathogens. The three main types are:

Viral Gastroenteritis

This is the most common type of gastroenteritis and is primarily caused by viruses like norovirus and rotavirus. These highly contagious viruses can spread through contaminated food, water, or surfaces. Symptoms include diarrhoea, vomiting, abdominal pain, and fever.

Bacterial Gastroenteritis

Infections due to bacteria like E. coli, Salmonella, or Campylobacter can also cause gastroenteritis. Bacterial gastroenteritis is often contracted through consuming contaminated food or water, or through close contact with an infected person or animal. Symptoms may include severe diarrhoea, abdominal cramps, nausea, vomiting, and sometimes fever.

Parasitic Gastroenteritis

This occurs when parasites like Giardia or Cryptosporidium infect the gastrointestinal tract. These parasites are usually found in contaminated food or water sources. Symptoms commonly include diarrhoea, abdominal pain, bloating, fatigue, weight loss, and nausea.

Complications Associated with Gastroenteritis

While Gastroenteritis usually resolves on its own, it can lead to several complications, especially in vulnerable populations. These include:

• Dehydration: This common complication is caused by loss of fluids and electrolytes from the body due to vomiting and diarrhoea. Infants, young children, and older adults are particularly vulnerable.

• Electrolyte imbalances: Gastroenteritis can disrupt the body's balance of electrolytes, such as sodium, potassium, and other essential minerals. Imbalances in electrolyte levels can lead to muscle weakness, irregular heart rhythms, fatigue etc.

• Malnutrition due to loss of nutrients: Frequent episodes of vomiting or diarrhoea can lead to malnutrition due to the loss of vital nutrients. This is particularly concerning for infants and young children whose growth and development depend heavily on obtaining adequate nutrition.

• Secondary infections or complications: Although rare, prolonged gastroenteritis can sometimes lead to secondary infections like bacterial infections or superinfections. Additionally, individuals with weakened immune systems or preexisting medical conditions may be at a higher risk of developing complications.

Risk Factors for Gastroenteritis

• Poor hygiene practices: Neglecting proper hand washing after using the restroom or before handling food can increase the risk of contracting gastroenteritis. Not maintaining cleanliness in food preparation areas can lead to contamination and subsequent infection.

• Consuming contaminated food or water: Eating improperly cooked or raw foods, especially meats, seafood, and eggs, drinking water from unsafe sources or consuming fruits and vegetables washed with contaminated water can also increase the risk.

• Close contact with infected individuals: Close contact with infected individuals, direct exposure to their bodily fluids or touching contaminated surfaces is another key risk factor. This is particularly common in settings such as schools, daycare centres, nursing homes, and hospitals.

• Weakened immune system: People with weakened immune systems and immunocompromised individuals, including those with chronic illnesses or undergoing treatments such as chemotherapy, are at higher risk.

Prevention Strategies for Gastroenteritis

• Following good hand hygiene: Wash hands frequently with soap and water, especially before eating or preparing food, after using the bathroom, and after coming into contact with someone who is sick. Remember to scrub hands thoroughly for at least 20 seconds to ensure proper cleanliness.

• Proper food handling and storage: Always wash fruits and vegetables before consuming them. Cook foods thoroughly, especially meat, poultry, eggs, and seafood. Avoid consuming raw or undercooked foods. Refrigerate perishable foods promptly to prevent bacterial growth.

• Drinking clean and safe water: Always drink water from safe sources or consider using a water purifier or boiling the water before consumption.

• Isolation and hygiene measures around infected individuals: As gastroenteritis is contagious, avoid spread by washing hands frequently, disinfecting contaminated surfaces , and using separate utensils, towels, and bedding to prevent cross-contamination.
