Some issues Dr. Chaithanya Mallikarjun, MD can help you with:

Anemia

Anemia is the most common blood disorder. It occurs when the body does not have enough red blood cells to carry oxygen to the tissues. Blood loss, insufficient red blood cell production, and red blood cell destruction are the three main causes of anemia. These issues may arise from such conditions as iron deficiency, heavy periods, ulcers, kidney disease, as well as some forms of cancer.

An individual with anemia will have the following symptoms: shortness of breath, weakness, dizziness, cold hands or feet, paleness, and irritability. Anemia is diagnosed when blood tests show low counts for hemoglobin, which is the protein responsible for carrying oxygen to different tissues throughout the body.

Treatments for anemia are dependent on the kind of anemia an individual has. For example, iron supplementation may correct iron deficiency anemia. For anemia caused by chronic kidney failure, chemotherapy treatments, and HIV/AIDS, a group of medications called erythropoiesis-stimulating agents may be prescribed.

Colectomy (Colon Resection)

Colectomy is surgery to remove all or part of the colon, or the longest part of the large intestine. The colon may be affected by diseases such as cancer or inflammatory bowel disease. In a colectomy, all or part of the colon that is infected, blocked, or cancerous is removed.

A colectomy may be performed by laparoscopic or open surgery. A laparoscopic colectomy requires several small cuts on the abdomen, and uses a thin tube with a camera, called a laparoscope. Laparoscopic colectomies are less invasive than open procedures. For some individuals, a laparoscopic colectomy may not be possible, and instead an open colectomy is performed. In an open colectomy, a large incision is made on the abdomen. Open colectomies typically require longer recovery periods.

After the incisions are made, a portion of the colon is removed, and the remaining ends of the colon are attached to each other in a procedure called anastomosis. Waste can continue to travel through the body as normal. However, in some situations, it may be necessary for the end of the colon to be attached to an opening in the abdomen, called a stoma. This procedure is called an ostomy. Types of ostomies include:

Colostomy, in which the remaining portion of the colon is attached to the abdominal opening.
Ileostomy, in which the small intestine is attached to the abdominal opening.

An ostomy bag will be attached to the skin to collect waste. If the entire colon is removed, either an ileostomy is performed, or the small intestine is connected to the anus and waste may pass through as normal.

Stomas may be permanent or temporary. If the stoma is temporary, the ends of the colon will be rejoined in a later procedure. Temporary stomas are generally used to allow time for the colon to heal following surgery.

A colectomy may take between one and four hours. Following the procedure, patients will need to consume a liquid and low fiber diet before gradually returning to their normal diet. Patients will need to stay in the hospital for three to seven days for monitoring. Full recovery and return to normal activity may take anywhere from a few weeks to several months.

Colonoscopy

Colonoscopy is the use of a special tool called a colonoscope (a thin, flexible tube with a camera on the end) to examine the inside of the colon and rectum. The tube is typically inserted anally, and it allows the physician to examine the large intestine from the inside. It may be done at any time to diagnose bowel problems, but routine colonoscopies are advised after the age of 50 to screen for colon cancer.

A colonoscopy may be performed to diagnose:

Intestinal ulcers
Polyps
Bowel cancer
An unidentified source of pain or bleeding in the intestine

Patients may be asked to drink only liquids in the days before a colonoscopy, or they may be given an enema to remove residual fecal matter. Before the exam, patients are given medication to help them relax, and then lay on their side on a table. The scope is inserted into the anus and gently moved all the way through the large intestine. Air may be pumped into the intestine to improve the view for the physician. Any polyps that are found will be removed. Then the colonoscope will be withdrawn. A colonoscopy is not usually painful, but patients may feel some bloating or have some cramps right afterward. If patients have polyps removed, they might experience a small amount of bleeding. Any side effects should go away within a few hours.
