Gastroenterologists are specialists who treat diseases of the digestive system and those affecting the gastrointestinal tract including the organs from mouth to anus ranging from indigestion to abdominal pain, appendicitis, jaundice, gallstones, lactose intolerance, hepatitis, reflux, ulcers, and hemorrhoids
Signs and Symptoms for Gastroenterological Conditions
More commonly known as colon or rectal cancer, this disease
tends to develop when cells in this particular region begin to rapidly grow out
of control.
A
majority of these cancers start as small polyps that can be precancerous.
Though most patients show no symptoms at this stage (asymptomatic), over time
these polyps can become cancerous. Depending on the size and how deep the
cancer has grown, the prognosis may vary and early stages tend to not show any
symptoms whatsoever.
Take
note of these colorectal cancer symptoms:
-
Gastrointestinal cramps or pains
-
Gassiness and bloating
-
Bowel habit change (constipation or diarrhea)
-
Bloody/tarry stools
-
Loss of weight
-
Loss of appetite
-
Feeling nauseous
-
Vomiting
-
Fatigue
Small pockets within the intestinal wall lining that tend to
form with age are known as Diverticula. If these become infected, this
progresses to what is known as diverticulitis and is commonly caused due to the
lack of dietary fiber in one's diet.
Symptoms
may include:
-
Severe abdominal pains
-
Fever
-
Nausea
-
Fatigue
-
Bloody/Tarry stools
Gastroesophageal Reflux Disease (GERD)
This particular disease is due to a reflux of acid on a frequent
basis, especially when stomach acid moves up and to the throat due to
abnormally relaxed lower esophageal sphincter muscles.
Common
GERD symptoms include:
-
Heartburn after meals (burning sensation in chest or throat)
-
Sour taste in mouth
You
can alleviate GERD by:
-
Refraining from belts or tight clothing that constrict the stomach
-
Keeping a healthy weight in check
-
Avoiding alcohol and cigarettes
-
Keeping meal portions smaller
-
Avoiding foods that trigger GERD symptoms
-
Waiting awhile before lying down after a meal
-
Keeping your head and neck elevated while sleeping
Inflammatory Bowel Disease (IBD)
The two main causes of IBD are Crohn's disease and ulcerative
colitis where ulcerative colitis affects the innermost lining of one's large
intestine and rectum, causing chronic inflammation and ulcers or sores to
develop. Whereas, Crohn's disease tend to include multiple different areas
throughout the entire digestive tract, often occurring towards the end of the
small bowel (the ileum) or the beginning. This disease can also affect the
entire bowel wall where areas that are affected can be interspersed between the
healthy sections of the colon.
Symptoms
of IBD may be associated with:
-
Inflammation triggered by overactive immune systems
-
Viral or bacterial triggers
-
Environmental triggers
-
Genetic factors
Other
symptoms of IBD may include:
-
Fatigue
-
Weight loss
-
Abdominal pains
-
Diarrhoea
-
Intermittent rectal bleeding
More commonly known as piles, haemorrhoids are swollen veins in
the anal and lower rectal region, typically occurring due to straining one's
bowel movements.
Symptoms
may be associated with:
-
A small sensitive and/or painful lump or lumps protruding from the anus
-
Pain, itching and/or discomfort around the anal region
- Painless bleeding during bowel movements
Irritable Bowel Syndrome (IBS)
This is a chronic gastrointestinal disorder that affects one's
large intestine with a range of symptoms that include:
-
Loss of appetite
-
Gassiness and/or bloating
-
Diarrhoea and/or constipation during intermittent periods
-
Abdominal pain that is relieved with bowel movement
Gastroenterological diagnosis by tests
Gleneagles' range of hospitals provides you with the best
diagnostic and screening services, all wrapped up in a modern and comfortable
setting. Your results will be reviewed by doctors who will explain and offer
the necessary treatment options based on your ailment, lifestyle and/or risk
factors.
Due to the nature of gastrointestinal conditions, a
wide variety of symptoms may surface thus a proper diagnosis should first begin
with a gastroenterologist questioning family medical history prior to a
physical examination. Additional lab tests and imaging may be required such as
these below:
Often used to check faecal occult blood tests
for colorectal screening, this test can help assess the patient's gut health by
taking into consideration the change in acidity (pH), colour and consistency of
stools. The presence of mucus, red and white blood cells, sugar, fat and bile
can help further understand the causes of indigestion, constipation, diarrhea,
mal-absorption and infection.
Sound waves are used to produce dynamic images
of organs that may not be accessed via other conventional means such as the
gallbladder, pancreas and liver.
This diagnosis allows for the close scrutiny of
the stomach and digestive tract. A long instrument resembling a long tube with
a camera called an endoscope is used to take images of the inter
gastrointestinal environment. For further diagnosis, biopsies may taken to be
microscopically examined to help in cancer cell detection.
Computed Tomography (CT) and Magnetic Resonance Imaging (MRI)
scans help give specialists a cross-sectional view of the abdominal organs.
This then helps them visualize the conditions of the internal structures of the
body.
As medical test used to detect polyps and other
various abnormal gastrointestinal growth, a camera is embedded at the end of a
flexible tube, which is then inserted via the anus. This allows specialists to
visually examine the large intestine and parts of the small intestine for any
abnormalities.
Liver function tests, blood counts and
pancreatic enzyme tests can help determine conditions such as parasitic, viral
or bacterial infections, lactose intolerance, celiac disease and diarrhoea.
These blood tests may often help exclude other serious illnesses.
Treatments for Gastroenterological Conditions
We aim to get you back on track to your regular
healthy daily life activities. Each treatment option like these listed below
will be recommended by our medical team largely depending on your individual
condition, and health and medical history.
The typical main treatment method for this
would be surgery to remove the cancer. Your doctor may also recommend
chemotherapy as well as radiation therapy before and after successful surgery.
The easiest path to treatment for this
condition would be diet improvement and sometimes antibiotics. Mild cases of
diverticulitis infection may only require rest, a liquid diet, stool softeners
and antibiotics. However, surgery may be recommended for more severe cases
along with a course of antibiotics and intravenous nutrition.
Gastroesophageal Reflux Disease (GERD)
Prescription drugs to neutralise, reduce and block excessive
stomach acid production may be prescribed. Drastic measures include surgery and
procedures such as these listed below may be recommended:
-
Fundoplication to tighten the muscle and prevent reflux by wrapping the top of
the stomach around the lower esophageal sphincter.
- Insertion of a LINX device, a string of magnetic beads, around the stomach
allowing for the magnetic elements of the beads to draw the junction closer
together yet still enable food to move through.
Inflammatory Bowel Disease (IBD)
In order to treat this condition, various drugs may be
prescribed to reduce inflammation and suppress the immune system that is
causing the inflammation, using antibiotics to treat any related infections.
Pain relief as well as anti-diarrhoea medication may also be prescribed.
As
bowel rest may reduce inflammation, nutrition through feeding tube inserts or
via intravenous injections may be recommended for more severe cases.
For
drastic measures, surgery to remove diseased parts of the large and/or small
intestine may sometimes be required for much more severe cases.
Stage 1 and 2 hemorrhoid development may require lifestyle
changes and minor medical treatment which may include diets with high fibre
foods, the usage of topical treatments, warm water soaks and anal area
cleanliness. Haemorrhoid symptoms often go away within one or two weeks.
However,
if persistent bleeding and painful haemorrhoids occur, our specialist team may
perform rubber band ligation, in which one or two small bands are placed at the
base of the haemorrhoid to cut off blood circulation. Alternatively, injections
(sclerotherapy) and coagulation via infrared and/or lasers may be recommended
for haemorrhoid size reduction.
If
surgery is recommended, the two main options include:
- Haemorrhoidectomy
- the most effective and complete way to treat severe or recurring
haemorrhoids.
- Stapled
haemorrhoidectomy or stapled haemorrhoidopexy - where blood flow to
haemorrhoidal tissue is blocked off. This process is typically used for
internal haemorrhoids. Though causing less pain, this procedure has a greater
recurring risk as compared to a regular haemorrhoidectomy
Irritable Bowel Syndrome (IBS)
Changes in your diet, or completely removing foods that cause
bloating may be recommended by your doctor. Depending on your range of
symptoms, fibre supplements, laxative or diarrheal medication may be prescribed
to you.
Certain
drugs may be prescribed to:
-
Ease diarrhea via reduction of muscular contraction and secretion of fluids in
the intestine, while increasing rectal muscular tone
-
Decrease overgrowth of bacteria
-
Increase fluid secretion in small intestines to help bowel movement
