Most people with diverticulitis have few or no symptoms. Twenty percent of those with diverticulitis will develop symptoms related to diverticulosis. The most common symptoms of diverticulitis include:
Diverticulitis is a condition in which diverticuli in the colon rupture. The
rupture results in infection in the tissues that surround the colon.
What is diverticulosis?
The colon (large intestine) is a long tube-like structure that
stores and then eliminates waste material. Pressure within the colon causes bulging pockets of tissue (sacs) that push out from the colonic walls as a person ages. A small bulging sac pushing outward from
the colon wall is called a diverticulum. More than one bulging sac is
referred to in the plural as diverticula.
Diverticula can occur throughout the colon but are most common
near the
end of the left colon referred to as the sigmoid colon. The condition
of having
these diverticula in the colon is called diverticulosis.
A
person with
diverticulosis may have few or no symptoms. When a diverticulum
ruptures and infection sets in around the diverticulum, the condition is called diverticulitis.
An individual suffering from diverticulitis may have
abdominal pain,
abdominal tenderness, and
fever. When bleeding originates from a diverticulum, it is
called
diverticular bleeding. A person who suffers the consequences
of diverticulosis in the colon is referred to as having
diverticular disease.
Diverticular disease is common in the Western world but is
extremely rare in areas such as Asia and Africa. Diverticular
disease
increases with age. It is uncommon before the age of forty, and
is seen in
more than fifty percent of people over the age of 60 years in the
United
States. Whereas most patients with diverticular disease have no
or few
symptoms, some patients will develop bleeding, rupture and infection
(diverticulitis),
constipation, diarrhea, abdominal cramps, and even colonic obstruction.
How do diverticula form?
The muscular wall of the colon grows thicker with age, although the cause of this thickening is unclear. It may reflect the increasing pressures required by the colon to eliminate feces. For example, a diet low in fiber can lead to small, hard stools which are difficult to pass and which require increased pressure to pass. The lack of fiber and small stools also may allow segments of the colon to close off from the rest of the colon when the colonic muscle in the segment contracts. The pressure in these closed-off segments may become high since the increased pressure cannot dissipate to the rest of the colon. Over time, high pressures in the colon push the inner intestinal lining outward (herniation) through weak areas in the muscular walls. These pouches or sacs that develop are called diverticula.
Diverticulitis (Diverticulosis) - Symptoms at Onset of DiseaseQuestion: The symptoms of diverticulitis (diverticulosis) can vary greatly from patient to patient. What were your symptoms at the onset of your disease?
Abdominal pain is pain in the belly and can be acute or chronic. Causes include inflammation, distention of an organ, and loss of the blood supply to an organ. Abdominal pain can reflect a major problem with one of the organs in the abdomen such as the appendix, gallbladder, large and small intestine, pancreas, liver, colon, duodenum, and spleen.
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Rectal bleeding (hematochezia) refers to the passage of bright red blood from the anus. Rectal bleeding may be moderate to severe and most bleeding comes from the colon, rectum, or anus. Common causes include anal fissures, hemorrhoids, diverticulitis, and more.
Diarrhea is a change is the frequency and looseness of bowel movements. Cramping, abdominal pain, and the sensation of rectal urgency are all symptoms of diarrhea. Absorbents and anti-motility medications are used to treat diarrhea.
Night sweats are severe hot flashes that occur at night and result in a drenching sweat. In order to distinguish night sweats that arise from medical causes from those that occur because one's surroundings are too warm, doctors generally refer to true night sweats as severe hot flashes occurring at night that can drench sleepwear and sheets, which are not related to an overheated environment.
Gas or "intestinal gas" means different things to different people. Everyone has gas and eliminates it by belching or farting (passing it through the rectum).
Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, abuse of laxatives, hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
E. coli is the most common cause of bladder infections. Bladder infection symptoms and signs include frequent urination, burning urination, and foul smelling urine. Mild bladder infections may go away by increasing one's intake of fluid. More severe infections may be treated with a few days of antibiotics.
Digestion is the complex process of turning food you eat into the energy you need to survive. The digestive process also involves creating waste to be eliminated, and is made of a series of muscles that coordinate the movement of food.
Duodenal diverticula (extramural or intramural), or duodenal diverticulum, is a pouch that is attached to the first part of the small intestine (duodenum). The cause of extramural diverticula is not clear, however, it may be congenital. Complications caused by duodenal diverticulum include rupture, gallstones, or pancreatitis. Extramural duodenal diverticula has no symptoms. Treatment is generally surgery.
Blood pressure is the force exerted by circulating blood on the walls of blood vessels. It constitutes one of the critically important signs of life or vital signs which include heart beat, breathing, and temperature. Blood pressure is generated by the heart pumping blood into the arteries modified by the response of the arteries to the flow of blood.
An individual's blood pressure is expressed as systolic/diastolic blood pressure, for example, 120/80.The systolic blood pressure (the top number) represents the pressure in the arteries as the muscle of the heart contracts and pumps blood into them. The diastolic blood pressure (the bottom number) represents the pressure in the arteries as the muscle of the heart relaxes following its contraction. Blood pressure always is higher when the heart is pumping (squeezing) than when it is relaxing.
The range of systolic blood pressure for most healthy adults falls between 90 and 120 mil...
