Gastrointestinal Tract Conditions (gut)

To understand conditions of the gut, an understanding of how it works is required:

• The primary function of the GUT is digestion. This is the processing of the foods and liquids that we consume to obtain and absorb the nutrients that we need, which are then used as energy and building blocks by our cells.
• Enzymes, hormones and good gut bacteria (gut flora) all play a role in the digestive process, whereby food and liquid are moved through the gut by a movement called peristalsis (wave-like muscle contractions)
• Valves (sphincters) within the gut ensure that food moves in one direction
  Waste products of the digestive process are excreted through the anus in the form of stool

These involve the gut and the digestive organs
The condition can be infectious (caused by micro-organisms) or non-infectious in nature

Most common cause of gut disease
Triggered by viruses, bacteria or parasites
Leads to gastroenteritis, an inflammation of the gut
Involves the stomach and the small intestine
Symptoms include diarrhoea, vomiting and abdominal pain
Dehydration is the main danger
Most cases are self-limited
In babies, patients with impaired immune systems, pregnant women and the elderly, it can however be potentially serious
Rehydration and infection control measures are pivotal in the management of gut infections
In some cases, antibiotics, anti-diarrheal, and/or absorbent medication may be indicated

An Inflammatory bowel disease (IBS) that mostly affects the part of the gut connecting the small intestine with the large intestine
The exact cause has not been determined, but family history and genetics may play a role
Most common symptoms are abdominal pain, diarrhoea, rectal bleeding, weight loss and fever
It is usually treated symptomatically, but in some cases medication to suppress the immune system may be required

This is similar to Crohn’s disease, however, it solely affects the large intestine
The body’s own immune system attacks the lining of the colon, causing sores and ulcers
Abdominal cramps, diarrhoea and bloody stool is experienced
Treatment includes dietary changes and medication to suppress the inflammation

These are hard deposits that form in the gallbladder when excess cholesterol, waste in bile or the gallbladder itself are not emptied properly
Sharp pain in the upper right abdomen, nausea and vomiting result
Medication is prescribed to dissolve the gallstones and in some cases, surgery may be required

Tears in the lining of the anus caused by constipation, hard and strenuous bowel movements, and/or diarrhoea
Most common symptoms are pain and bleeding after bowel movements
Medication to relieve pain, anal sphincter muscle relaxants and a diet rich in fibre are recommended. In some cases, surgery may be required

Inflammation of the blood vessels in the rectum and the anus due to strenuous bowel movements, constipation and/or diarrhoea
Painful or itchy lumps around the anus and blood in the stool ensue
Introducing more fibre into the diet, creams, or suppositories can assist in relieving pain or itching. In some cases, surgery may be required

Pouches form in weak areas of the gut lining, particularly in the colon, and become inflamed and/or infected
The exact cause is not yet known, but a lack of fibre in the diet and obesity are risk factors.
Abdominal pain and fever follow
A diet rich in fibre and antibiotics are prescribed. In some cases, surgery may be required

• Drink at least 8 glasses of water per day
• Include fibre in the diet
• Take a probiotic
• Exercise
• Avoid the overuse of antibiotics
• Avoid sugars and refined carbohydrates

Visit your doctor when you have:

• Persistent abdominal or rectal pain and fever
• Blood or pus in the stool
• Diarrhoea that persists for more than 2 days
• Vomiting in combination with diarrhoea that prevents fluid intake
• Signs of dehydration
