Bariatric Surgery is a permanent procedure that helps patients reset hunger and satiety. It changes to your digestive system to help you weight lose.

Exercise and/or diet often fail to offer effective cure treatment for obese people. Doctors recommend Bariatric Surgery for such people; the procedure can produce effective weight reduction. Studies have even revealed that the process has lessened down the death rates for acute obese people.

Doctors suggest an effective and nourishing diet for the patients. They also recommend accommodating lifestyle changes in post-operative procedures too.

Surgery Principles

Doctors perform the operation to control your food intake so that organs like the stomach and intestines are not strained from much foodie suppression.

Our digestion process begins in the mouth as soon as we complete the chewing process. These are then transferred to our stomach after making mix-up reactions with saliva and various other enzyme-enriched secretions.

In this region, it combines with digestive juices; then these are broken down to release nutrients and energy calories into our bodies. The process excels as it moves into your duodenum. At the duodenum, it combines with bile and various other ingredients like pancreatic juices.

Bariatric surgery aims at interrupting the patient’s digestion process. It hinders the breaking of food into nutrient and energy constituents. These are then absorbed into our body system.

Reduction in the available nutrient and calorie quantum makes effective losing in weight. Losing weight for overweight people brings up healing.


Bariatric surgery is a major surgery process held under general anesthesia. Like other similar procedures, it carries several potential health-related risks. A potential candidate may have both short-term and continual health risks.

Common risks associated with such a process include:

  • Profuse bleeding
  • Infection that could be fatal.
  • Adverse reactions to the anesthetic medicines.
  • Blood coagulation.
  • Breathing problems like shortness of breath.
  • Other breathing organ issues.
  • Leaks in the gastrointestinal system.
  • Death.

Bariatric weight-loss surgery carries several long-term risks followed by complications too. The nature and extent of such potent vary according to surgery types and characteristics.

Potential risks include:

  • Hernia.
  • Ulcer.
  • Malnutrition.
  • Acid reflux.
  • Hypoglycemia, i.e. low blood sugar.
  • Dumping syndromes; may finally lead to diarrhea, flushing, lightheadedness, nausea, or vomiting.
  • You may have to undergo a revised procedure for some innate difficulties.
  • Patient’s demise.

Again, jeopardizes associated with bariatric procedures vary by its type too. For instance, processes like the gastric bypass and gastric sleeve have many common risks; yet, huge uncommon factors lie between these two.

You can adopt measures to lessen such risks. You can do it by:

  • Decreasing the Body Mass Index.
  • Do much more exercise.
  • Controlling evil addictive habits like smoking and drinking.

Following tests are required to make the patient fully optimized about the process. Entire test cubicles should be over within six months before the surgery process. Properly done case finding would facilitate the potential to have the best available care to you.


Your doctor will recommend the following tests. The primary care physician can help you in completing most of these:

  • Blood Work

It combines the following tests:

  • Fe Panel.
  • HgbA1C
  • Homocysteine, C-reactive protein, lipoprotein a – it helps assess cardiac risk factors.
  • Lipid Panel.
  • B12
  • A complete metabolic panel including calcium and liver function tests.
  • Thyroid function tests.
  • Folate, combined with thiamine determination tests.
  • EKG
  • CXR
  • Cardiac echo; Combines HX of phen-fen or long-standing sleep apnea; there could be a cardiac risk screen too.
  • You will have instructions to stop smoking immediately. Illusory addictions like the use of steroids and taking immune suppressants should also help up with immediate effects.

Stress Test

It includes abnormal cardiac echo, family HX, IDDM, and HTN. A 20-pack year medical history is needed for people above 50 years of age. The doctors put stress upon factors like elevated lipids, CRP, lipoprotein a, homocysteine.

Greenfield Filter

The test is recommended if your medical history includes blood freezing in the leg and lungs. Other hues may comprise severe sleep apnea in some less-weight people.

Such clotting could be fatal and the Greenfield filter resists that. These filters are removed after 2-4 weeks after your surgery is over.
