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.
One in every 20 people develop a kidney stone at some point in their life. A kidney stone is a hard mineral and crystalline material formed within the kidney or urinary tract. Kidney stones symptoms and signs are, blood in the urine and pain in the abdomen, flank (lower back), or groin. A number of different conditions can lead to kidney stones including: gout, hypercalciuria, people with inflammatory bowel disease, kidney disease, and hypoparathyroidism. Some medications also increase the risk of kidney stones.
Crohn's disease is a chronic inflammatory disease,
primarily involving the small and large intestine, but which can
affect other parts of the digestive system as well. Abdominal pain, diarrhea, vomiting, fever, and weight loss are
common symptoms.
Gastroenteritis (viral gastroenteritis, stomach flu) is an infection caused by a variety of viruses that results in vomiting and/or diarrhea. Even though it is often called the "stomach flu," it is not caused by the influenza viruses. Viruses that can cause gastroenteritis (stomach flu) include: rotaviruses, adenoviruses, caliciviruses, astroviruses, Norwalk virus, and a group of Noroviruses. Gastroenteritis is not caused by bacteria. The main symptoms of gastroenteritis include vomiting and watery diarrhea, however, headache, fever, and abdominal cramps (stomach ache) may also be present.
Appendicitis is an inflammation of the appendix. Appendicitis often causes
fever, loss of appetite, and right lower
quadrant abdominal pain. Delay in surgery can result in appendix rupture with potentially serious complications.
Gallstones are stones that form when substances in the bile harden. Gallstones (formed in the gallbladder) can be as small as a grain of sand or as large as a golf ball. There can be just one large stone, hundreds of tiny stones, or any combination. The majority of gallstones do not cause symptoms.
Diverticulitis is a condition in which diverticuli in the colon rupture. The rupture results in infection in the tissues that surround the colon. Diverticulitis symptoms include: abdominal pain, abdominal cramps, diarrhea, constipation, and bloating. Treatment methods include prescription medications, and in some cases, diverticulitis surgery.
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.
Norovirus infection causes stomach flu, or gastroenteritis. It's a very contagious illness with symptoms that include nausea and vomiting, diarrhea, stomach cramps, fever, headache, chills, and muscle aches. Norovirus infection cannot be treated with antibiotics, so treatment focuses on maintaining proper hydration.
Liver cancer is the fifth most common cancer in the world and the majority of patients with liver cancer will die within one year as a result. Patients with associated cirrhosis caused by chronic hepatitis B or C infections, alcohol, and hemochromatosis are at the greatest risk of developing liver cancer. Many patients with liver cancer do not develop symptoms until the advanced stages of the tumor which usually makes prognosis poor. The combination of an imaging study (ultrasound, CT, or MRI scans) and an elevated blood level of alpha-fetoprotein will most effectively diagnose liver cancer, while a liver biopsy can make a definitive diagnosis. Medical treatments, including chemotherapy, chemoembolization, ablation, and proton beam therapy, are not very effective. Surgical removal of the tumor or a liver transplant may be most effective in certain cases.
GERD (gastroesophageal reflux disease) is a condition in which the acidified liquid
contents of the stomach backs up into the esophagus. The symptoms of uncomplicated GERD are heartburn,
regurgitation, and nausea. Effective treatment is available for most patients with GERD.
Endometriosis is the growth of cells similar to those that form the inside of the uterus, but in a location outside of the uterus. Endometriosis implants are most commonly found on the ovaries, the Fallopian tubes, outer surfaces of the uterus or intestines, and on the surface lining of the pelvic cavity. They can also be found in the vagina, cervix, and bladder. Treatment of endometriosis can be with medication or surgery.
There are many types of ovarian cancer, epithelial carcinoma is the most common. Women with a family history of ovarian cancer have an increased risk of developing the disease. Some ovarian cancer symptoms include abdominal pain, nausea, diarrhea, constipation, and abnormal vaginal bleeding, however, they usually do not present until the disease has progressed. Early diagnosis is important for successful treatment.
Colon cancer is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.
Liver disease can be cause by a variety of things including infection (hepatitis), diseases such as gallstones, high cholesterol or triglycerides, blood flow obstruction to the liver, and toxins (medications and chemicals). Symptoms of liver disease depends upon the cause; however, common symptoms may include nausea, vomiting, upper right abdominal pain, and jaundice. Treatment depends upon the cause of the liver disease.
A hernia is an opening or weakness in the muscular structure of the wall of the abdomen. This defect causes a bulging of the abdominal wall. Symptoms of a hernia include pain or discomfort and a localized swelling somewhere on the surface of the abdomen or in the groin area.
Pancreatic cancer is a malignant tumor of the pancreas. Pancreatic cancer has been called a "silent" disease because early pancreatic cancer usually does not cause symptoms.
Though uterine cancer's cause is unknown, there are many factors that will put a woman at risk, including: over age 50, endometrial hyperplasia, using hormone replacement therapy, obesity, using tamoxifen, being Caucasian, having colorectal cancer. Symptoms of cancer of the uterus (endometrial cancer) include abnormal vaginal bleeding, painful urination, painful intercourse, and pelvic pain. Treatment depends on staging and may include radiation therapy or hormone therapy.
Though the cause of stomach cancer is unknown, risk factors for stomach cancer include diet, H. pylori infection, smoking age, gastritis, stomach surgery, family history, and pernicious anemia. Symptoms include stomach discomfort, feeling full after a small meal, nausea and vomiting, and weight loss. Treatment depends upon staging and may involve surgery, radiation therapy, or chemotherapy.
In lactose intolerance, the digestive system cannot digest lactose (the main sugar in milk). Symptoms of lactose intolerance include diarrhea, flatulence, abdominal pain, abdominal bloating, abdominal distention, and nausea. There are several tests to diagnose lactose intolerance. Treatment is generally made with dietary changes, supplements, and adaptation to small amounts of milk.
An ectopic pregnancy is a pregnancy located outside the inner lining of the uterus. The majority of ectopic pregnancies occur in the Fallopian tube. Symptoms include abdominal pain, amenorrhea, and vaginal bleeding. Treatment options include observation, medication, or surgery.
Clostridium difficile (C. difficile) is a bacterium, and is one of the most common causes of infection of the colon. C. difficile spores are found frequently in hospitals, nursing homes, extended care facilities, and nurseries for newborn infants. They can be found on bedpans, furniture, toilet seats, linens, telephones, stethoscopes, fingernails, rings, floors, infants' rooms, and diaper pails. They even can be carried by pets. Antibiotic-associated (C. difficile) colitis is an infection of the colon caused by C. difficile that occurs primarily among individuals who have been using antibiotics. Treatment for C. difficile colitis hydration, replenishment of electrolyte deficiencies, discontinuing the antibiotic that caused the colitis, and using antibiotics to eradicate the C. difficile bacterium.
Ovarian cysts are fluid-filled, sac-like structures within an ovary. Causes of ovarian cysts are numerous. Symptoms of an ovarian cysts may be pain in the belly or pelvis. Treatment of an ovarian cysts depends on type of cyst.
Chlamydia, a type of bacteria that causes an infection, is spread through sexual contact. Most of the time, women with chlamydia have no symptoms. Antibiotics are an effective treatment for chlamydia.
Ulcerative colitis is a chronic inflammation of the colon. Symptoms include abdominal pain, diarrhea, and rectal bleeding. Ulcerative colitis is closely related to Crohn's disease, and together they are referred to as inflammatory bowel disease. Treatment depends upon the type of ulcerative colitis diagnosed.
Abdominal aortic aneurysm is a ballooning or widening of the main artery (the aorta) as it courses down through the abdomen. The most common cause of aortic aneurysms is
"hardening of the arteries" called arteriosclerosis.
Celiac disease is a result of an immune reaction to gluten, a protein found in wheat or related grains and present in many foods that we eat. Celiac disease causes impaired absorption and digestion of nutrients through the small intestine. Signs and symptoms of celiac disease include malabsorbption (diarrhea, foul smelling gas, bloating, and increased amounts of fat in the stool) and malnutrition (weight loss, edema, anemia, bruising easily, neuropathy, and infertility). Treatment for celiac disease is a gluten free diet, and at times if necessary, medications
Pancreatitis is a rare disease in which the pancreas becomes inflamed, occurring when digestive enzymes are activated and begin attacking the pancreas causing damage to the gland. There are two types of pancreatitis, acute and chronic. Most commonly caused by alcohol or gallstones, it can lead to bleeding in the gland, serious tissue damage, infection, and cysts. Enzymes and toxins may then enter the bloodstream and seriously injure organs, such as the heart, lungs, and kidney.
Colitis means inflammation of the colon. The colon, also
known as the large intestine or large bowel,
constitutes the last part of the digestive tract. The colon is a long, muscular
tube that receives undigested food from the small intestine. It removes water
from the undigested food, stores the undigested food, and then eliminates it from the body through
bowel movements. The rectum is the last part of the colon adjacent to the anus. The common symptoms of colitis include:
abdominal pain,
diarrhea, and
sometimes, rectal bleeding.
There are many different types of colitis
with different causes. Some examples of colitis include:
infectious colitis caused by bacteria (such as
shigella,
Campylobacter, E.
coli, and C.
difficile)
infectious colitis caused by a virus (such as
cytomegalovirus [CMV])
