Nutrition Tips After Bariatric Surgery

Posted on August 26, 2011 by admin

The weight loss battle has new weapons that have shown some positive results. Bariatric surgery can help obese people reduce their body weight to healthier levels by making the size of their stomachs smaller. When all else has failed, bariatric surgery may be their only hope. Nutrition after bariatric surgery is vital to keeping results.

When all else has failed, bariatric surgery may bring hope. The two most common bariatric procedures are gastric banding and gastric bypass. The gastric banding process, in which the upper part of the stomach is contained within a band to reduce its size. This is considered the safer and easier of the two. Gastric bypass is a more invasive operation in which a section of the stomach is shut off and part of the intestine bypassed. Long-term weight loss has been shown with both these bariatric surgeries. Other results such as  improving cardiovascular risk factors and diabetic issues and reducing mortality from obesity-related health issues, have occurred after bariatric surgery.

As with any  operation, a doctor should be consulted to talk over the risks and rewards of bariatric surgery. You should also discuss any dietary concerns, at whatever stage, with a physician as well before considering bariatric surgery.

Nutrition After Bariatric Surgery

Bariatric surgery will cause your body to absorb foods differently. Nutrition after bariatric surgery is important to health. This trouble in absorbing some nutrients, such as iron, calcium and B vitamins, can place your health at risk.  Supplements may be needed to work against these deficiencies and avoid osteoporosis, anemia and  pernicious anemia. Doctors may suggest combining an adult-strength multivitamin with iron, a separate B complex supplement, D supplement and 1,500 milligrams of calcium each day to help fill in the nutrion gaps.

After bariatric surgery your stomach will be less than one-half cup. The days of eating the large meals will be over. To avert poor nutrition, bariatric surgery patients must learn to eat frequent small meals. if you have poor calorie intake, this  will result in your body entering starvation mode. Therefore, it is better to consume four to five small meals each day. Some small steps to help with  nutrition after bariatric surgery may be easier than you think. You should take little bites, eat slow, chewing each bite thoroughly before swallowing, and learn to read your body’s signals telling  you when you are full.

Once the physician has determined that the body is responding to the liquid diet, the patient will move on to pureed foods. Some examples would be protein drinks, cream of wheat, pureed fruit, and yogurt. It is very important to drink a lot of fluids (but not during meals) and maybe take a vitamin supplement.

The smaller stomach will not be able to hold as much food as before and becomes full faster. Bariatric surgery weight loss occurs from feeling full after eating less calories. If the patient continues to eat, the body will send out distress signals in the form of pain, nausea, or vomiting.

Other Tips After Bariatric Surgery
