It has been found that patients with severe obesity tend to suffer from infections after heart surgery. The morbid obesity seems to interfere with proper recovery from a bypass operation.
Heart patients who also have morbid obesity tend to experience some sort of infection after surgery and thus have to prolong their hospital stay. The research was published in Journal of the American Heart Association. The fact was plain as the light of day.

Those who had a normal weight range did not experience any prolonged infections after coronary bypass surgery. The patients who were severely obese tended to experience three times the rate of post-operative infections as their slimmer cousins.
The operation is meant to redirect the blood flow via other vessels than those which are clogged into the heart muscle. Thus what we learn from this study is that effective infection treatment and prevention is a must for those obese people undergoing heart surgery.
The study took place in Canada. It involved a database that included 7560 heart patients. They were from a wide variety of races and ethnicities. After they had bypass surgery between 2003 and 2014, they were slotted in accordance with their BMI and weight and height comparisons.
The result was that they formed a total of five groups. There were those with a normal weight, those who were overweight, an obese class of people, a second class of obese people and last but not least a very severely obese class of people.
The BMIs of each of these categories ranged between 18.5 and 40 (or higher). 20% of the patients had a normal weight. 40.7% were overweight. The three classes of obese people (I, II and III) formed 25.7%, 9.2% and 4.4% of the population sample respectively.
As compared to the normal weight population, those who were heftier tended to be younger and had diabetes, hyperlipidemia, hypertensive symptoms and lung disease.
They were also more prone to having had angioplasty in the past. Those with severe obesity had a 56% higher chance of facing complications a month after surgery.
Those who were moderately obese had a 35% greater chance of facing infections. Some of the patients stayed for a longer period of time while others stayed only for a few days in the post-operative stage. These were divided on a 50:50 basis in the population sample.

Those who were both obese and diabetic (a condition known as diabesity) stayed 3.2 times longer than their normal disease-free cousins. Such data proves that post-operative care is of the utmost importance. At least for the severely obese, it is a must. Why the severely obese individuals tended to face infections remains unclear though.
