Are we losing sight of overall health? Here’s what the science says

The craze for brand spanking new medicine within the GLP-1 (Glucagon-like peptide 1) and GIP (Gastric inhibitory polypeptide) analog class, higher recognized underneath the commerce names Ozempic and Wegovy, is outstanding, but it surely’s not completely unprecedented within the historical past of pharmaceutical blockbusters.

The quantity of prescriptions and the finances allotted to them by public medical health insurance schemes are exploding, as are the earnings of the businesses that manufacture them.

A part of the recognition of those medicine owes to social networks, however these are usually not at all times the very best supply for well being info. Relating to the topic of weight reduction, each fantasy and prejudice come into play. This works to the detriment of everybody’s well-being, however significantly those that are already stigmatized.

As specialists within the philosophy of medication (Université de Montréal), vitamin and meals science (Université Laval), the sociology of medicine (Université de Montréal) and endocrinology (Institut de recherches cliniques de Montréal), we really feel it’s a necessity to step again and take inventory of each the guarantees and the restrictions of those new therapies.

One of the best of each worlds

GLP-1/GIP analogs had been initially developed to manage glycemia (blood sugar ranges) in individuals with Kind 2 diabetes, thereby stopping the issues related to this illness. When research had been carried out to evaluate their security and efficacy, it was found that these medicine additionally led to weight reduction. This prompted new analysis which confirmed that at larger doses, the medicine may result in very vital weight reduction, from 15 to 25% of the beginning weight.

The mode of motion of those medicine on blood sugar regulation is obvious: they simulate incretin hormones which, in flip, improve insulin secretion. Weight reduction, however, was solely defined after the actual fact: along with the pancreas, these molecules additionally act on the mind by regulating the feeling of satiety and, not directly, on the abdomen by slowing gastric emptying. These two mixed results scale back urge for food and result in weight discount.

That is how a brand new use for the drug appeared, at which level the corporate Novo Nordisk started advertising and marketing the identical drug underneath two completely different names: Ozempic to deal with Kind 2 diabetes, and Wegovy to handle weight problems.

A brand new period

GLP-1/GIP analogs are a welcome therapeutic breakthrough at a time when the prevalence of Kind 2 diabetes and weight problems is exploding and affecting individuals youthful and youthful.

These illnesses significantly have an effect on girls, members of racialized teams and socio-economically deprived populations. The bodily and psychological struggling these trigger and the prices related to treating them are each appreciable. So the arrival of recent weapons within the therapeutic arsenal is a supply of hope.

Draconian adjustments in way of life are actually efficient. However they’re very troublesome to implement and preserve over time for causes that transcend the person sphere; on the one hand, genetic predisposition performs a serious position within the improvement of Kind 2 diabetes and weight problems; on the opposite, as a result of these situations are multifactorial, administration of them have to be complete to be efficient and lengthy lasting: it should mix medical interventions but additionally dietary, practical, psycho-social, environmental and even institutional interventions.

Assist companies of this type do exist, however solely in giant college hospital facilities to which many individuals don’t have entry. Nor do many individuals have easy accessibility to wholesome and diverse meals choices, sports activities services or social and psychological help.

Treating the results however not the causes

To be efficient over the long run, GLP-1/GIP analogs have to be taken constantly: with out drastic way of life adjustments, the burden that was misplaced is regained inside a yr of stopping, and glycemic management is compromised as soon as once more.

In different phrases, the medicine deal with the results of Kind 2 diabetes and weight problems however not their causes. And but a few of these causes are modifiable: for instance, in accordance with Statistics Canada, lower than half the Canadian inhabitants (49.2% for adults; 43.9% for younger individuals and youngsters) achieves the really helpful quantity of weekly bodily exercise. In response to the identical supply, meals insecurity impacts round 14% of the Québec inhabitants (22% in Alberta).

Pharmacological remedy, even when it permits a person to eat much less, doesn’t essentially imply that particular person will eat higher. Equally, shedding pounds doesn’t imply one will grow to be extra lively or more healthy. So these new medicine don’t treatment Kind 2 diabetes or weight problems. Nor do they stop these illnesses from growing, though they do assist to restrict the numerous issues to which they offer rise.

Prescribe and deal with

A drug reminiscent of Mounjaro is as efficient at weight reduction as bariatric surgical procedure. A lot simpler to manage and far much less dangerous, it might be an actual sport changer within the remedy of weight problems. Prescribed immediately by household docs and distributed in pharmacies, it might even be rather more accessible and simpler to manage for many who want it.

This raises the query of prices and reimbursement, however not solely that: prescribing will not be the identical as treating. Right here, the producers are following the suggestions of the well being authorities: this remedy have to be preceded by a cautious evaluation, then administration, and above all an in depth and common monitoring of weight loss plan, bodily exercise, psychological well being, and if mandatory, socio-economic help.

This requires not solely time that GPs don’t have, but additionally co-ordination with different gamers within the health-care community. The issue will not be whether or not the remedy can be efficient, however what can occur whether it is. Dropping 25% of your physique weight in only a few months has critical penalties, which aren’t at all times helpful: it entails a lack of physique fats, but additionally of muscle mass, which is related to intense fatigue. Nor ought to we underestimate the problem of adapting bodily and psychologically to a physique transformation of this scale. Reducing weight would not resolve all the pieces, and expectations should stay practical.

What classes can we be taught?

The scientific effectiveness of GLP-1/GIP analogs in lowering the issues related to Kind 2 diabetes and weight problems is indeniable. Nevertheless, these medicine are usually not appropriate for everybody, and they’re actually not miracle cures that may make it attainable for one to regain well being with out making any adjustments to way of life or atmosphere.

We should keep in mind that their success, each industrial and medical, can also be the results of a failure: that of our societies to stop these illnesses, to advertise wholesome existence and to develop environments conducive to the well being of all.
