Abdominal rigidity

What is an abdominal rigidity?

Abdominal rigidity is a protective mechanism, called guarding, in the abdomen. It is an abdominal pressure-induced response of the muscles of the stomach. The stomach becomes stiff as an involuntary response to pressure on the abdominal region. This can worsen when the stomach is touched. This is the stomach’s way of guarding itself against pains.

It is different from when you purposefully flex your muscles or the stiffness associated with severe gas.

When this becomes recurrent, seek medical help.

 

Abdominal rigidity and abdominal pain

If abdominal rigidity is a response to pains, any condition that therefore induces abdominal pains can cause an abdominal rigidity. It is therefore right to conclude that abdominal pains and abdominal rigidity coexists. Appendicitis happens to one of the leading causes of abdominal rigidity. Disorders in any of the organs located in the abdominal cavity –kidneys, ureter, liver, gallbladder, large and small intestines, stomach, large vein and artery (vena cava and aorta respectively) and pancreas – can cause abdominal pains.

And so will those in the pelvic regions. Organs in the pelvis include; fallopian tubes, uterus, lower ureters, ovaries, rectum, prostate gland in men and bladder.

Lower lungs abnormalities can sometimes also cause abdominal pains and stiffness.

Causes of abdominal rigidity

It is mostly age-dependent, especially in the elderly adults. Younger persons can also experience this in certain conditions as you will see later in this article.

Some of these causes are; abdominal trauma, peritonitis, pancreatitis (inflammation of the pancreas), abdominal abscess, inflammation of the gallbladder (cholecystitis), cancer and intestinal blockage. It can also be caused by holes in the stomach, gallbladder or intestines.

 

In adolescent women;

  • Dysmenorrhea (painful menstruation)
  • Pelvic inflammatory disease contracted from sexually transmitted infections
  • Ovarian cysts
  • Peritonitis
  • Pregnancy

In older children;

  • Urinary tract infections (UTIs)
  • Appendicitis
  • Ingested poison

In Infants;

  • Colic
  • Gastroenteritis (digestive irritation caused by a virus)
  • Viral infection
  • Pyloric stenosis (narrowing of the stomach outlet)

There is something interesting about abdominal pains. They are mobile. They can be projected. That is they can travel cause organs that are not actually diseased to feel their pains. This kind of pain is called referred pains.

For example, appendicitis can begin as a right, lower quadrant pain and then transit to towards the belly button.

Stomach ulcers refer pains to the upper and left quadrant of your abdomen. Gallstones project pains to the upper left upper quadrant of your abdomen because they are found in the upper right part of the abdomen.

Diagnosis of abdominal rigidity

It is always advisable not to resort to self-help to alleviate the pains should you experience abnormal rigidity especially if it persists for days. Doing this can make it really difficult for the doctor to diagnose you properly.

When you visit a doctor, you will be asked the following questions so as to take your medical history;

  1. When did the symptoms start?
  2. Are the pains dull, sharp, reoccurring (coming on and off), or travels to another area of your body?
  3. How long do the pains last?
  4. What were you doing when the pains began?
  5. What made the pains better or worse?
  6. Did you experience other symptoms other than the pains?
  7. When did you start experiencing those symptoms?
  8. When did you take your last meal?

Answering these questions will help the doctor decide on what action to take next.

After reviewing your medical history, a physical examination will be conducted on you.

Next, after a physical examination, the doctor may instruct that you go for the following tests;

  1. Abdominal ultrasound scans for your abdominal or pelvic regions
  2. Abdominal X-rays
  3. Abdominal CT scan
  4. Urinalysis
  5. Complete blood count
  6. Creatinine test (an indication of kidney functioning)
  7. Liver function tests
  8. Serum electrolytes test to assess your potassium, sodium, chloride and bicarbonate concentration
  9. Blood urea nitrogen test
  10. Stool test to check for the presence of blood in it.

 

Treatment options for abdominal rigidity

Treatment depends on the cause. It might be mild or aggressive.

Mild cases will require self-care, monitoring, self-care or prescription of antibiotics based on the underlying cause.

If the case is severe, aggressive treatment will be adopted. Examples include;

  1. Intravenous fluids therapy to prevent dehydration
  2. Nasogastric feeding where you are fed through a tube connected to your nose
  3. Intravenous antibiotics
  4. Surgery

 

Complications associated with abdominal rigidity

  1. Bacterial infestation of the blood due to infection of the abdomen. This can result in shock.
  2. Abnormal heart rhythm, shock and kidney failure can occur due to prolonged and severe dehydration and electrolyte imbalance.
