Some issues Dr. Gintaras Antanavicius, 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.

Gastric Bypass Surgery

Gastric bypass surgery is a procedure that promotes weight loss by reducing the stomach and altering how the digestive system absorbs and processes food. The procedure treats morbid obesity, where one's weight impairs day-to-day function or poses serious health risks. Gastric bypass surgery is used only after other weight loss treatments are unsuccessful.

Generally, gastric bypass surgery is performed on patients who have a BMI of 40 or greater, or a BMI of 35 or greater with a weight-related health condition such as type 2 diabetes. Bariatric surgeons frequently expect patients to first attempt natural weight loss for about six months to prove to the surgeon that the patient is capable of maintaining a post-surgery diet and exercise regimen.

For obese patients, gastric bypass surgery has many potential health and weight benefits. Gastric bypass surgery restricts the amount of food the stomach contains, as well as:

Reduces the calories the stomach absorbs
Alters gastrointestinal hormones, which help to heal obesity-induced metabolic syndrome
Suppresses appetite
Alleviates conditions caused or exacerbated by obesity, such as obstructive sleep apnea, heart disease, and type 2 diabetes
Contributes to mental health by improving self-esteem

During gastric bypass surgery, the stomach is stapled to reduce its size, and a small hole is created in the stomach and attached to the middle section of the small intestine. This direct connection between the stomach and the middle of the small intestine creates a channel for some food to bypass the normal route. By bypassing the upper small intestine and larger region of the stomach, food is not fully absorbed and patients do not retain the same amount of calories as before. This procedure is also sometimes referred to as "Roux-en-Y" gastric bypass surgery. Some bariatric surgeons may perform a "laparoscopic bypass" which uses a tiny camera (laparoscope) to guide the procedure.

Gastric bypass surgery is performed with general anesthesia and as preparation, a liquid diet is required for two weeks prior to undergoing the surgery. After the surgery, patients will spend about two days in the hospital and may miss work for two to three weeks. In the first month after the surgery, patients are only able to consume small portions of liquid or soft food. Even after reintroducing solid food, patients feel full quickly, sometimes after eating just two or three tablespoons. Some patients experience "dumping syndrome" (rapid processing of food into the small intestine), which is common during the recovery process. Gastric bypass surgery patients must also make permanent lifestyle changes. For example, gastric bypass patients are required to take vitamins for life after surgery and required to forever avoid certain foods, such as alcohol, sugar, and high fat food.

While the gastric bypass recovery process can be challenging, surgery results are usually swift: most gastric bypass surgery patients lose nearly half to two thirds of their starting weight within two years of surgery.

Weight Loss Surgery (Bariatric Surgery)

Bariatric or weight-loss surgery is a surgical procedure performed to help significantly obese patients lose weight when more traditional methods, such as dieting and exercise, have not helped. Depending on the type, these surgeries change the gastrointestinal tract to limit how much food can be eaten and also change how food is absorbed by the body. Of the various bariatric surgeries available, the most common is gastric bypass.

By far the most common of the gastric bypass surgeries is called Roux-en-Y. During this surgery, part of the stomach and small intestine are detached from the gastrointestinal tract, in order to make the tract smaller. The surgeon divides the stomach into two parts. The working stomach, at the end of the esophagus, is now tiny - only the size of a walnut. This makes patients feel full after eating a small amount of food. Then the small intestine is also divided, and after bypassing a section of the small intestine to reduce food absorption, the intestine is attached to the small stomach pouch. The patient now has a working stomach and intestine like before, only much smaller.

Because gastric bypass is used to treat extreme obesity, it can reduce the risk of some of the problems associated with obesity. Gastric bypass can help treat or reduce the risk for such conditions as heart disease, high blood pressure, sleep apnea, and type 2 diabetes. However, it is a major surgery and also carries risks itself. Any surgery can lead to infection, bleeding, or blood clots, and weight loss surgery in particular carries risks of leaks in the gastrointestinal system, malnutrition, bowel obstructions, and vomiting.

Typically patients are considered candidates for gastric bypass surgery if they have a BMI greater than 40, or sometimes if they have a BMI between 35 and 40 but are suffering from obesity-related illnesses such as diabetes. The outlook is generally good, with most patients losing between 50-75% of their excess weight in 1-2 years. However, patients must follow strict diet guidelines so that the stomach can heal, starting with no food at all, then followed by a liquid diet for some time. For many severely obese patients who have tried strict diets before without success, gastric bypass surgery is the tool that allows them to finally achieve their weight loss and health goals.
