Obesity

Diabetes Obesity and diabetes have a strong correlation. Up to 90% of the those who develop diabetes in adulthood are overweight. The Gastric Bypass and the Gastric Sleeve methods have a clear effect on the regulation of high blood sugar levels and in most of cases it cures type 2 diabetes and improves blood sugar control in type 1 diabetics.

Cardiovascular Disease These are one of the most common causes of death in the world today, and there is a clear connection between heart disease and obesity. For patients undergoing weight loss surgery, blood pressure is often lowered. Studies also show that weight loss surgery reduces the risk of death in myocardial infarction.

High blood pressure A Swedish study shows that high blood pressure is more dangerous for the heart in the obese population compared to the slim and normal weight population. Gastric Bypass surgery has a strong positive effect on the normalization of blood pressure.

Biliary disease Overweight increases the cholesterol turnover and there is an increased risk of cholesterol crystals precipitating into the bile causing the formation of gallstones. In the presence of gallstones, bile surgery may be considered necessary before the overweight surgery.

Reflux (acid reflux) In case of overweight, the fat in the abdominal cavity compresses the stomach and the stomach content tends to be pushed up in to the esophagus. Weight reduction significantly reduces the risk of acid reflux.

Sleep apnea (paused or shallow breathing during sleep) It is well known that many obese persons suffer from sleep apnea. Sleep apnea itself is a risk factor for cardiovascular disease and premature death, but it is also a risk factor that can give rise to an increased proportion of complications in obesity surgery. In case of suspicion of sleep apnea, the patient is first referred to a sleep apnea clinic for Continuous Positive Airway Pressure (CPAP) treatment before determining surgery. After surgery, all patients with CPAP treatment are better and approximately 80-90% are cured from sleep apnea syndrome.

Cancer With an increasing degree of body weight, an increased risk of cancer is seen. In men, commonly in the bowel and prostate regions, while overweight women run greater risk of tumors in the breast and abdomen. Weather the effects are due to overweight or of the fat tissue's hormonal activity, is unclear. Nor is it clear what weight reduction means for these tumor risks.

Muscle and joint pain There is a strong connection between most types of musculoskeletal problems and obesity. Weight loss related to overweight surgery leads to improvements in both pains in weight-bearing joints (ankle, knee and hip), as pains in parts of the body that are not weight-bearing. Most orthopaedics recommend weight loss before a patient undergoes hip or knee surgery because this significantly improves the prognosis.

Menstrual Disorders Fat tissue is actively involved in hormone turnover. Studies show that the more overweight you are, the more common are menstrual cycles without ovulation. Overweight reduces fertility and therefore weight loss can have a positive effect on some forms of infertility.

Psychosocial disorders Obesity is a sickness that often leads to a low quality of life and the consumption of antidepressants (and many other medicines) used in psychiatry can increase the risk of developing severe obesity. Several studies demonstrate positive effects on the quality of life measurements following obesity surgery.
