Irritable Bowel Syndrome
Irritable Bowel Syndrome or Irritable Bowel disease is a condition that affects nearly 20% of the adult American population. While most of the time, the causes for Irritable bowel syndrome (IBS) are mild, in rare cases, it may be indicative of ulcerative colitis or Crohn's disease. It is noticed that women are more prone to develop IBS than men, leading to the belief that hormonal changes may have a bearing on the condition. IBS involves a functional disorder of the large intestine. It usually has no structural or biochemical causes.
Typical symptoms that affect persons suffering from irritable bowel syndrome are gas (flatulence), bloating and mucus/blood in stool. Constipation or diarrhea is also noticed. The patient suffers from cramps. Other symptoms can range from fever and nausea to weight loss and vomiting of bile. In most cases of irritable bowel syndrome, the symptoms are mild. But in chronic cases of IBS, the symptoms are persistent and can affect the quality of the life of the patient. It is noticed that stress, medications, certain foods or stimuli may trigger the IBS symptoms. Some persons notice worsening of symptoms on consumption of milk, alcohol, chocolates or dairy products. Gastroenteritis can trigger an attack of irritable bowel syndrome.
A gastroenterologist can help you diagnose and treat this condition with dietary changes and medication.
Stool studies, functional assesment of the GI tract and colonoscopy can aid in screening for IBS. Colonoscopy involves examination of the coloon with a small flexible tube. This helps to rule out ulcerative coliits or colorectal cancer. Anti-inflammatory drugs such as sulfasalazine and antibiotics such as metronidazole can attack the germs in the intestine. Anti-diarrheal medication, laxatives or painkillers can provide relief from symptoms of irritable bowel disease. Dietary changes that are likely to be prescribed include eating at regular times, drinking plenty of water, restricting fatty foods and reducing dairy products. Moderate exercise is also helpful. Gradual increase in fiber content in the diet provides relief for many. Fiber supplements are sometimes prescribed. Ulcerative colitis or Chrohn's disease must be treated differently.
MRI
Magnetic Resonance Imaging (MRI) represents a breakthrough in medical diagnostics and research. Nearly 60 million investigations with MRI are performed every year worldwide. This imaging technique was awarded the Nobel Prize in Physiology in 2003. MRI has been used since the beginning of 1980s. MRI is primarily used in medical settings to produce high quality images of the inside of the human body. Magnetic field of radio waves energy is used to capture pictures of organs and structures inside the body. The MRI scan used magnetic and radio waves and therefore there is no exposure as in X rays or any other damaging forms of radiation. Since radiation is not used, the procedure can be repeated without problems.
MRI is used to examine the joints, spine and the soft parts of the human body such as liver, kidneys and spleen. An MRI scan is used in the diagnosis of diverticulitis, irritable bowel syndrome, intestinal gas, chronic pain, liver cancer, pancreatic cancer, Cardiomyopathy, Devic's syndrome and headaches in children. It is used in to study specific conditions such as:
Trauma to the brain, bleeding and swelling in the head
Brain aneurysm
Stroke
Brain tumor
Tumors or inflammation of the spine
Trauma of the spinal cord
Problems of vertebrae or intervertebral discs of the spine
Tears and aneurysms in the structure of heart and aorta
Information on glands and organs in the abdomen
Structure of joints, soft tissues and bones of the body
To direct surgery or to defer surgery.
During a MRI Scanning procedure, patient is made to lie in a closed area inside a magnetic field. This creates claustrophobic sensation in certain patients during the procedure. Normally a mild sedative is given prior to the MRI scan and this helps to alleviate the claustrophobic sensation. The new open MRI is open on three sides and this helps to alleviate the feeling of claustrophobia. The new open MRI scanner provides quality imaging with highest performance specifications with a powerful and stronger magnet. Scanning is also done much faster. It has the ability to detect diseases more accurately.
Crohn's Disease
Crohn's Disease is an intestinal disorder characterized by inflammation of the digestive tract. Crohn's disease is characterized by ulceration of the intestines and affects the GI tract. The exact cause for Crohn's disease is unknown thought it is suspected to be due to bacterial infection. Crohn’s disease is an inflammatory bowel disease that differs from ulcerative colitis in that the inflammation and ulceration is noticed in all the layers of the intestines. It is noticed that people of Jewish descent are at increased risk for developing Crohn's disease. The symptoms are similar to irritable bowel syndrome.
20% cases of Crohn's disease are heriditary in nature. Symptoms of Crohn's disease are rectal bleeing and diarrhea. There is abdominal pain and weight loss. Nutritional deficiencies are noticed with patients suffering from Crohn's disease caused due to poor absorption. There may be arthritis, skin problems or gallstones.
Blood tests are done to check for presence of certain antibodies that may help diagnose Crohn's disease. A colonoscopy can aid the doctor in examining the lining of the intestines and checking the extent of inflammation. A small sample may also be taken for biopsy. CT scans and small bowel x-rays can help in identifying the areas of inflammation within the intestines. Anti-inflammatory drugs are prescribed to control inflammation. Corticosteroids such as Prednisone are used in treating Crohn's disease. Antibiotics are used to treat bacterial overgrowth in the small intestine. Surgery is often resorted to in most cases of Crohn's disease. A part of the intestine is removed or any blockage is removed. But Crohn's disease is likely to resurface after some years of surgery.
