Understanding Stomach Infections: Definition, Causes & Types

 

What are Stomach Infections?

Stomach Infections are a broad term used to describe various gastrointestinal issues that affect the ability of the body to absorb water and digest food properly. It can also increase the rate at which things enter your GI tract. This can result in nutrients not being absorbed properly and hamper the digestion of food which can cause the fluid content in your colon and intestines to increase. In addition to these digestive symptoms, stomach infections can damage the walls of the intestine as infectious agents pass the digestive tract. Stomach infections can result in diarrhoea, vomiting and other unpleasant symptoms.

 

Causes of Stomach Infections

Stomach infection can be caused by a wide range of pathogens like bacteria, viruses or parasites that can affect different parts of your stomach.

 

Types of Stomach Infections

 

Bacterial Stomach Infection

Bacterial stomach infections include foodborne infections and food poisoning.

The common sources of bacterial stomach infections are: -

• Salmonella
• coli
• Clostridium Perfringens
• Listeria
• Staphylococcus or staph infection[AP1]

 Bacterial Stomach infections can be caused by ingesting contaminated foods, with some kinds of foods posing a greater risk than others like:

• Undercooked or raw meat, eggs or poultry
• Unpasteurised dairy and juices
• Contaminated water
• Food, especially meat and eggs products that are not refrigerated well
• Deli meats
• Unwashed or raw fruits and vegetables.

Also, individuals with bacterial stomach infections may spread the bacteria to the food they touch, potentially infecting someone else who consumes that food.

 

Viral Stomach Infections

Viral stomach infections are common and are often referred to as stomach flu.

Norovirus is a viral stomach infection and is one of the most common foodborne illnesses worldwide. Vaccines are effective in preventing some types of viral infections, including rotavirus.

 

Parasitic Stomach infections

Intestinal helminths or worms and protozoan parasites cause these stomach infections. The two most common parasitic infections include Giardiasis and Cryptosporidiosis, spread through contact with human faeces in soil or contaminated water.

Some parasitic infections can also spread from animals to humans, like toxoplasmosis, which people can come in contact with through cat faeces.

 

Common Stomach Infection Symptoms: What You Need to Know

 

Diarrhoea and Loose stools

 

What is Diarrhoea? How is it Different from Loose Stools?

 

Stools that are more watery and loose than your regular stools are called loose stools. Everyone experiences loose stools occasionally; some may even experience loose stools daily. However, you have diarrhoea if you have more than three episodes of loose stools daily.

Diarrhoea refers to loose, watery and possibly more frequent bowel movements. It can be present alone or accompanied by other symptoms like nausea, abdominal pain, nausea and vomiting.

 

Causes of Diarrhoea and Loose Stools

• Viruses- Viruses that can result in diarrhoea are Norwalk virus or norovirus, enteric adenoviruses, astrovirus, cytomegalovirus and viral hepatitis. Rotavirus is known to cause acute childhood diarrhoea commonly.
• Bacteria and parasites- Exposure to any pathogenic bacteria like E. coli or parasites in contaminated food or water can cause diarrhoea, a common bacterial stomach infection symptom.
• Medications- Many medications can cause diarrhoea. Antibiotics treat infections by killing bacteria, but they also kill good bacteria. This disrupts the natural balance of bacteria in your intestines and causes diarrhoea.
• Lactose intolerance- Lactose is a sugar in milk and other dairy products. People who have difficulty digesting lactose after consuming dairy products may experience diarrhoea.
• Artificial Sweeteners- Some chewing gums and other sugar-free products contain non-absorbable sugars like Sorbitol, erythritol and mannitol that can cause diarrhoea in some people.

Loss of Appetite and Weight Loss

 

Understanding Loss of Appetite and Weight Loss

Anyone can experience weight loss, and there could be many reasons that could be the cause. People may lose the desire to eat, lose interest in food, or feel nauseous. Loss of appetite is often accompanied by weight loss and fatigue if a person does not eat enough to sustain the body.

The medical term for loss of appetite for a prolonged period is called anorexia. Other short-term causes for loss of appetite are cold, flu, respiratory infections, a bacterial stomach infection symptom, viral infections, constipation, upset stomach, acid reflux, food poisoning, allergies, food intolerances, pregnancy, stress, hormonal imbalances, medication side effects or alcohol and drug use.

 

Treatment and Prevention Options

• A doctor may prescribe certain medications to increase appetite and reduce other symptoms like nausea.
• If loss of appetite is due to depression or anxiety, talking therapies or taking antidepressants can be helpful.
• If your doctor thinks a specific medication is causing your appetite loss, changing the dosage or the drug may help.

• Eating several small meals a day instead of three big meals.
• Make these meals high in protein and calories so that your body is not deprived of nutrients and energy
• Adding herbs, spices, and other flavourings may encourage interest in eating
• Eating meals in relaxed social settings can make eating enjoyable
• Light exercise like a short walk can increase appetite
• Drink plenty of fluids to prevent dehydration

 

Dehydration and Fatigue

Understanding Dehydration and Fatigue

Dehydration means your body ends up losing more fluids than it takes in. If you're ignorant about the situation, your condition could worsen and get serious. Babies, children and older adults are at a higher risk of dehydration. Fatigue is often a symptom that comes along with dehydration.

• Have consumed too much alcohol
• Excessive sweating after exercising

Treatment and Prevention options

• The standard treatment for dehydration involves drinking plenty of fluids if you are experiencing dehydration. If you are already sick or ill, you will find it hard to swallow, so start with small sips of water and then gradually increase the quantity. It would help if you drank enough such that your urine appears pale and clear in colour.
• If you are sick or have diarrhoea and are losing a lot of fluid, you need to replenish the sugar, salt and minerals your body has lost.
• Your doctor will prescribe oral rehydration solutions you can mix with water and drink.
