Conditions Treated

The following conditions are some of the most common conditions treated by specialists in this area. These specialists offer expert care for many other related medical problems. If you need care for a condition not listed here, please call (888) 352-RUSH (7874) to find a doctor who can help you.

  • Achalasia is a rare disorder of the esophagus that drastically limits your ability to move food and liquids through your esophagus to your stomach.
  • Most anal cancers are squamous cell carcinomas that grow on the skin lining the inside of the anus. Anal cancer is rare and, if caught early, usually curable.
  • An anal fissure is a tear in the lining of the anus, or the lower part of the rectum, where stool passes out of the body.
  • Bile is a substance the  liver makes to help digest fat. Bile ducts carry it from the liver to the gallbladder and then, during digestion, to the small intestine. Bile duct cancer is rare, but the experienced doctors at Rush have expertise in treating it.
  • Biliary Atresia

    Biliary atresia occurs when the ducts (tubes) that carry bile from the liver to the gallbladder are blocked. This blockage can be life-threatening if it is not treated. The first symptom of biliary atresia in newborns is jaundice, a yellowing of the skin and eyes.
  • Blood in stool is a common symptom of hemorrhoids, anal fissures and many other conditions, including colorectal cancer. It can appear bright red, or it can turn stool black and tarry.
  • Breast cancer is the most common cancer in women. It can develop in several locations, including the milk duct (the tube that carries milk to the nipple) and the milk lobule (where milk is produced).
  • Alcohol, infections, toxins and genetic disorders can cause liver damage, including inflammation, scarring and disease. If left untreated, liver disease develops into cirrhosis, a chronic, life-threatening condition.
  • Colorectal cancer develops in the colon or rectum, two sections of the large intestine. Most colorectal cancers begin as polyps, or small lumps, that slowly turn into cancer over time.
  • Constipation is often defined as having a bowel movement fewer than three times a week. Other symptoms include hard stools, difficulty or straining when passing stools and pain during a bowel movement.
  • Cushing’s Syndrome

    Cushing’s syndrome is a hormonal disease in which the body is exposed to high levels of the hormone cortisol. Exposure to high levels of cortisol can occur from taking synthetic hormones (glucocorticoids) to treat conditions that cause inflammation, including asthma and certain autoimmune disorders.
  • Diverticulosis is when you have pouches that bulge out from your colon. Diverticulitis is when the pouches get infected or inflamed.
  • Esophageal cancer is cancer of the esophagus, the tube that takes food from the mouth to the stomach. Adenocarcinoma, the most common type of esophageal cancer in the United States, can result from gastrointestinal reflux disease (GERD) and Barrett’s esophagus.
  • Familial adenomatous polyposis is an inherited condition that will lead to colon cancer if untreated. It is marked by abnormal benign growths, or polyps, in the colon (the large intestine) or rectum.  
  • Fecal incontinence, also called bowel incontinence or anal incontinence, is the inability to control bowel movements.
  • Fistulas are abnormal connections that form between an organ, vessel or intestine and another part of the body. While they sometimes close on their own, they often require treatment.
  • The gallbladder stores bile, a substance the liver makes to help digest fat. The bile duct carries it from the liver to the gallbladder and then, during digestion, to the small intestine. Gallbladder cancer is rare, but the experienced doctors at Rush have expertise in treating it.
  • Gallstones

    Gallstones are stones that form from liquid in the gallbladder. They range in size from very tiny to the size of a golf ball. If a gallstone blocks the entrance to the bile duct, it can cause pain in the upper right belly, which is known as a gallbladder attack.
  • When heartburn causes stomach acid to leak into the esophagus, it can damage the esophagus and lead to gastroesophageal reflux disease (GERD).
  • Gastrointestinal Stromal Tumor

    Gastrointestinal stromal tumor (GIST) is a tumor of the gastrointestinal (GI) tract. Not all GISTs are malignant (cancerous): Some GISTs are benign (noncancerous). GISTs that are cancerous are treated differently than other gastrointestinal cancers, so it is important for specialists to determine whether a tumor is a GIST.
  • Gastroschisis is a birth defect that causes a hole in a baby’s abdominal wall. When this occurs, the baby’s intestines protrude from the body on one side of the umbilical cord. 
  • Hemorrhoids are swollen veins near the anus or lower rectum.
  • Hiatal Hernia

    A hiatal hernia, also known as diaphragmatic hernia, is a condition in which the upper part of the stomach bulges through an opening in the diaphragm. It is possible to have a hiatal hernia with no symptoms. But some people have heartburn related to gastroesophageal reflux disease, or GERD. Medicine can help relieve symptoms of hiatal hernias. Losing weight, not smoking and avoiding heavy meals can also help. If medicine and lifestyle changes do not work, surgical treatment is an option.
  • Hirschsprung’s Disease

    Hirschsprung’s disease is a genetic disorder in which certain nerves are missing from a person’s intestines. These missing nerves are responsible for moving stool along the intestines. This absence of nerves causes people with Hirschsprung’s disease to experience chronic constipation and obstructed intestines.
  • Human papillomavirus (HPV) is the most common sexually transmited disease, or STD. This extremely common infection affects the genitals of men and women and in some instances can lead to genital warts and cancer.
  • Hyperthyroidism, often called overactive thyroid, is a condition caused by too much thyroid hormone. Thyroid hormone comes from the thyroid gland, a small, butterfly-shaped gland in the front of the neck.
  • Inguinal Hernia

    Inguinal hernia is when tissue bulges through a weak area of abdominal muscle, potentially causing pain and other symptoms. Although the hernia is not life-threatening, it will not get better or go away on its own. Surgical repair will likely be recommended if the hernia is painful or grows.
  • The pancreas is an organ that helps the body digest food and use it as energy. The two main types of pancreatic cancer are exocrine pancreatic cancer, which is the most common, and endocrine pancreatic cancer.
  • Paraganglioma

    Paragangliomas are rare tumors that form near the carotid artery, along nerve pathways in the head and neck, and in other parts of the body. Paragangliomas are a type of neuroendocrine tumor.
  • Pelvic organ prolapse happens when organs can become dislodged and bulge out of the vagina or the anus. This happens when the pelvic floor — muscles and other tissues that support the bladder, uterus and other organs — becomes weakened or damaged.
  • Pheochromocytoma

    Pheochromocytomas are rare neuroendocrine tumors that form in the adrenal glands, which sit on top of the kidneys and produce hormones such as adrenaline (epinephrine) and dopamine. A pheochromocytoma can cause the body to produce too many of these hormones.
  • Pilonidal disease, also called pilonidal dimple, develops in the crease between the buttocks. It can result in an abscess, cyst or pit.
  • Pyloric Stenosis

    Pyloric stenosis is the narrowing of the opening between the stomach and the small intestine. This condition can prevent food from moving normally out of the stomach, which in turn can cause vomiting and other symptoms. Pyloric stenosis most commonly occurs in babies younger than 6 months old.
  • Radiation Proctitis

    Radiation proctitis is inflammation of the rectum that results from radiation to the pelvic area. It may occur as a side effect of radiation therapy used to treat cancers of the uterus, prostate or rectum.
  • Skin cancer is the uncontrolled growth of abnormal skin cells.
  • Small Intestine Cancer

    Small intestine cancer is cancer that begins in the small intestine, which connects your stomach to your large intestine. It is rare, but people with Crohn’s disease or celiac disease have a higher risk of developing it.
  • Soft tissue sarcomas are cancerous tumors that begin in the muscle, fat, nerves, tendons, blood vessels or connective tissues. Most are found in an arm or leg, or the abdomen (stomach) area.
  • When ingested, food travels from the mouth to the esophagus to the stomach, a small pouch where juices break food down before it enters the small intestine. Cancer that develops in the stomach usually starts in its inner lining.
  • Thyroglossal Duct Cyst

    Thyroglossal duct cyst is a small lump in the center or front of the neck that can occur if the thyroglossal duct does not fully disappear — as it should — during an embryo’s development. These cysts typically appear in young children and can grow over time, potentially causing swallowing or breathing problems.
  • Thyroid nodules are very common and usually don’t cause any symptoms or require any treatment. In a small number of cases, though, they may be cause for concern.
  • Urinary incontinence is the loss of bladder control.
  • Varicose veins are bulging, twisted veins that can be seen directly under the skin. They occur when the one-way valves in the legs that keep blood flowing to the heart do not work normally.
