Science of Obesity – The Best way for Losing Weight


Obesity globally

Every year that die from Being overweight or obese globally. Indeed being overweight and obese is that the fifth risk for global death. Most of this burden really comes from the diabetes that’s out there,from ischemic cardiopathy related to being overweight and obese, and in fact,increased risk of cancer related to being obese.

Obesity men and women

There is a study called the Framingham Heart Study, and this shows that if you’re obese and a non-smoker, women lose seven years of life and men lose about six years of life,but if you’re obese and a smoker, both women and men lose a minimum of 13 years of life.

That’s quite significant. Obesity can virtually affect every organ of your body. we are able to try to study the complications of obesity by splitting them up into three sections—metabolic, mechanical, and mental. If we start with the metabolic complications First, obesity is associated after all with a really high risk of type II diabetes which ends up in a true disease burden. Obesity increases your risk of disorder, including coronary artery disease, the danger of strokes, the danger of heart attacks, dyslipidaemia—that’s abnormalities with cholesterol, and increased risk of heart condition.

Risk of Obesity


 Obesity is related to an increased risk of gallstones, liver disease, which may attain fibrosis and cirrhosis, and in fact, it’s going to then cause the necessity for liver transplants. Currently, alcoholic disease is that the major cause for liver transplants, but obesity, liver disease disease and progression of that’s said to be probably the foremost common cause for a liver transplant within the years to come back. Obesity also affects respiratory illness. 

We see increased rates of obstructive sleep apnoea in our patient population and also Exacerbation of asthma. Moving to other metabolic problems, after all the increased risk of cancer is additionally increased in our population. This increases risk of cancers such as breast cancers, colorectal, endometrial, ovarian, pancreatic cancers, amongst many others. If we then advance to the mechanical complications of obesity, of course, we all know that an increased weight is related to problems with lower back pain and osteoarthritis.

 Finally, wondering psychopathy which of course could be a really, really important a part of this triad of complications, we all know that a lot of of our patients with obesity have depression and anxiety.

Of course, this burden of disease really must be tackled and sometimes it’s substantially ignored once we manage our patients. There are many options available for weight loss but the cornerstone of of these options, of course, is lifestyle interventions, so dietary changes and increased exercise within our lifestyles. For some patients, lifestyle alone isn’t enough so we’ve got to seem to other options, Including pharmacotherapy and bariatric surgery.

Pharmacotherapy is very useful in achieving weight loss and that we do have a spread of agents that we are able to select from a number of these mimic a number of our natural hormones, our satiety hormones that talk to our brain to mention that we are full. These interventions are often effective in achieving and maintaining weight loss.

Moving on from pharmacotherapy, there are some endoscopic options like the gastric balloon and also the EndoBarrier which are endoscopically placed into our gut. Again, these are found to be useful in achieving weight loss and maintaining weight loss although these procedures are temporary and once the device is removed, then the satiety signal is removed and not sustained. Finally, we’ve bariatric surgery, which has been shown to be an efficient thanks to both slenderize and maintain weight with time, with studies showing maintained weight loss up to twenty years and beyond.

The three commonest procedures worldwide are the gastric band, the sleeve gastrectomy, and therefore the Roux-En-Y gastric bypass. These procedures would require lifelong follow-up, especially nutritional supplementation lifelong, and it’s vital that if patients are considering bariatric surgery, which after all has been shown to be very successful arrested of the many of the comorbidities that I’ve spoken about to this point, that they’re assessed by an obesity physician to debate the pros and cons of surgery and whether it’s suitable for them.

Our bodies are designed in such how on preserve energy and defend us from times of famine. When we thin through a diet, for instance, our gut hormones change in such the simplest way on increase our hunger hormones – that’s ghrelin — and to decrease our satiety hormones,and after all making us feel more hungry.

What’s really interesting is that even one year after we finish our diet, our gut hormones still remember that we’ve lost calories and also the hunger hormones remain high and also the satiety hormones remain low; that’s, they haven’t gone back to baseline. Not only that,our basal rate after weight loss is lower; that’s, the energy required for all our metabolic processes is a smaller amount than it accustomed be. So, on balance, once we slenderize because of the changes within the gut hormones and also the undeniable fact that we require less calories to keep up our basal metabolic processes means it’s that much harder to stay that weight loss off, in time.
