Guide to Gastrointestinal Diseases: Symptoms, Causes, and Treatment

Gastrointestinal (GI) diseases are a group of ailments that affect the digestive tract, including the oesophagus or food pipe, stomach, small intestine or small bowel, large intestine (colon), rectum, and anus. GI diseases can range from mild discomfort to severe debilitation and significantly impact an individual’s overall health and wellness. In this comprehensive blog, let’s explore the different types of digestive system diseases, their causes, symptoms, and effective treatment options.

What are Gastrointestinal Diseases?

Gastrointestinal diseases are a broad category of conditions that affect the organs and structures involved in the digestive process. GI diseases can be classified into two main types: functional gastrointestinal diseases and structural gastrointestinal diseases.

A. Functional Gastrointestinal Diseases:

Functional gastrointestinal diseases are characterised by disruptions in the normal functioning of the digestive system without any visible structural abnormalities. These conditions are often related to how the digestive system works rather than a specific problem with the organs.

Examples of functional gastrointestinal diseases include:

• Irritable Bowel Syndrome (IBS)
• Functional dyspepsia
• Functional abdominal pain syndrome
• Functional constipation
• Functional diarrhoea

B. Structural Gastrointestinal Diseases

Structural gastrointestinal diseases are characterised by visible abnormalities or changes in the physical structure of the digestive system. Underlying medical issues or injuries often cause these conditions. Examples of structural gastrointestinal diseases include:

• Hernias
• Diverticulosis and Diverticulitis
• Inflammatory Bowel Diseases-Crohn’s Disease and Ulcerative Colitis
• Peptic Ulcers
• Gallstones
• Pancreatitis

Causes of Gastrointestinal Diseases

Gastrointestinal diseases can have a variety of causes, such as:

• Diet: A diet high in processed foods, low in fibre, or containing triggers like lactose or gluten can contribute to GI issues. Consuming contaminated water and foods can lead to infections and gastrointestinal diseases like cholera and dysentery.
• Lifestyle Factors: Stress, sedentary lifestyle, and poor sleep can increase the risk of gastrointestinal problems or exacerbate pre-existing conditions.
• Infections: Viral, bacterial, or parasitic infections in the digestive tract can lead to gastrointestinal problems.
• Structural Abnormalities: Issues with the structure or anatomy of the digestive system, such as hernias or growths, can cause GI problems.
• Autoimmune Disorders: Conditions like Crohn’s disease and ulcerative colitis, which involve an overactive immune system, can damage the digestive tract.
• Medications: Certain medications, such as antibiotics or long-term use of NSAIDs, can disrupt the balance of gut bacteria and lead to GI issues.
• Genetics: Some gastrointestinal diseases, like celiac disease, have a strong genetic component.

Symptoms of Gastrointestinal Diseases

The symptoms of GI diseases can vary greatly and depend on the specific condition and the affected part of the digestive system. Some common symptoms include:

• Abdominal pain or discomfort
• Bloating
• Constipation
• Diarrhoea
• Nausea and vomiting
• Heartburn and acid reflux
• Unintentional weight loss
• Blood in the stool
• Difficulty swallowing

Now, let’s take a closer look at some of the most common gastrointestinal diseases that doctors treat:

Constipation

Constipation is a common medical condition characterised by infrequent or difficult bowel movements. Various factors, including diet, lack of physical activity, certain medicines, and underlying medical conditions, can cause it. Constipation symptoms include hard, dry stools, excessive straining during bowel movements, and feeling incomplete evacuation.

Irritable Bowel Syndrome (IBS)

IBS is a functional GI disorder that manifests as recurrent abdominal pain, bloating, and changes in bowel habits, such as diarrhoea or constipation. It is often triggered by stress, certain foods, or other factors and can significantly impact an individual’s quality of life.

Haemorrhoids

They are veins in the lower rectum or anus that become swollen. They can be internal (inside the rectum) or external (around the anus). Symptoms of haemorrhoids include rectal bleeding, itching, pain, and a feeling of fullness or discomfort in the rectum.

Anal Fissures

It is a small tear or crack in the anal lining causing severe pain, bleeding, and difficulty with bowel movements. Anal fissures are often result from constipation or passage of hard stools.

Perianal Abscesses

A perianal abscess develops near the anus or rectum. It can cause pain, swelling, and redness in the affected area. A bacterial infection often causes perianal abscesses.

Anal Fistula

It is an abnormal connection or passageway between the anal canal (inner lining) and the skin around the anus. It can cause pain, drainage, and recurrent infections.

Colon Polyps and Cancer

Small growths can develop in the colon or rectal lining. While many polyps are benign, some can develop into colorectal cancer over time. Regular screening for colon polyps and cancer is essential for early detection and treatment.

Can Gastrointestinal Diseases Be Prevented?

While some gastrointestinal diseases may not be entirely preventable, there are several steps people can take to lower their risk and maintain a healthy digestive system:

• Adopt a Healthy Diet: Eating a diet rich in fibre, vegetables, fruits, and whole grains can promote regular bowel movements and lower the possibility of certain GI issues.
• Stay Hydrated: Drinking an optimal amount of water can help prevent constipation and other digestive problems.
• Exercise Regularly: Daily exercising improves digestion and reduces the risk of gastrointestinal conditions like diverticulosis and IBS.
• Manage Stress: Chronic stress can disturb the normal functioning of the digestive system. Practising stress-reducing techniques, like meditation or yoga, can be beneficial.
• Maintain Good Hygiene: Proper handwashing and food preparation can help prevent the spread of infectious gastrointestinal diseases.
• Avoid Smoking and Excessive Alcohol Consumption: Alcohol and tobacco can increase the risk of certain GI conditions, such as peptic ulcers and pancreatitis.

Treatment of Gastrointestinal Diseases

The treatment modalities of gastrointestinal diseases depend on the specific condition, its underlying cause, and the severity of symptoms. Here are some common treatment approaches:

• Dietary and Lifestyle Changes: Modifications to diet, like increasing fibre intake or avoiding trigger foods, effectively manage certain GI conditions. Regular physical activity, good quality sleep, and stress management can also be beneficial, says “Dr. Nikhil Bondade.”
• Medications: Prescription or over-the-counter medications may help alleviate symptoms, reduce inflammation, or address underlying causes. Examples include antacids, laxatives, antidiarrheals, and antibiotics.
• Surgical Interventions: In some cases, doctors may advise surgical procedures to address structural abnormalities or complications, such as removing haemorrhoids or repairing hernias.
• Complementary Therapies: Some individuals may find relief from gastrointestinal symptoms through the use of complementary therapies, such as probiotics, herbal remedies, or mind-body practices.

Conclusion

Gastrointestinal (GI) diseases encompass numerous disorders, underscoring the importance of a comprehensive treatment approach. If you are experiencing persistent or concerning gastrointestinal symptoms, talk to a doctor for proper treatment. Don’t hesitate to schedule an appointment with a gastroenterologist or primary care physician to get the care you need and take the first step towards better digestive health.
