ISLAMABAD, January 25 (Online): The number of people with type 2 diabetes rose nearly fourfoldTrusted Source between 1980 and 2014, according to the World Health Organization (WHO)Trusted Source.
\nType 2 diabetes has many risk factors, including some genetic and environmental factors, but increased body weight and lack of exercise are both linked to the condition.<\/p>\n
Diabetes is characterized by a chronic rise in glucose (blood sugar), due to insulin resistance in cells. Insulin is a hormone that allows the uptake of glucose by cells in the body, where it is used an as energy source.
\nInsulin is produced in response to increased glucose levels in order to facilitate this. However, some peoples\u2019 cells become less responsive to insulin, meaning that their glucose levels rise.<\/p>\n
Obesity as a factor in diabetes
\nObesity can increase the risk of insulin resistance occurring, and can in fact trigger it. This may occur as some of the hormones and immune cells and molecules that play a role in insulin resistance are released by fat cells.
\nObesity can also make it difficult to treat diabetes as some of the treatments that people with type 2 diabetes receive for their symptoms can cause weight gain, which can in turn worsen glucose control.
\nWeight loss can lead to remission of type 2 diabetes in some patients. This weight loss can be achieved via lifestyle changes or through weight loss surgery, as a study published in JAMA SurgeryTrusted Source in 2020 shows.<\/p>\n
A trial carried out in the United Kingdom, published in The LancetTrusted Source in 2018, showed that 50% of people with type 2 diabetes who received support to lose weight through dietary changes were in remission a year later.
\nThese studies involved significant intervention, whether they involved bariatric surgery for weight loss or lifestyle intervention, and were all based on clinical trials.<\/p>\n
While they proved weight loss can be an effective way to achieve remission of type 2 diabetes, there is a lack of real-world data available about the likelihood, and sustainability of remission.<\/p>\n
Does weight loss send diabetes into remission in real-world settings?
\nTo remedy this, a group of researchers from the Chinese University of Hong Kong conducted an analysis of data for patients enrolled in the Risk Assessment and Management Programme for Diabetes Mellitus (RAMP-DM), which provides regular assessment of people with diabetes living in Hong Kong.
\nTheir paper appears in PLOS Medicine.<\/p>\n
The researchers looked at the data for 37,326 people with type 2 diabetes who were enrolled on the programme within a year of diagnosis between 2000\u20132017 and followed up until 2019. The researchers looked at weight loss, whether or not weight loss had been sustained, and blood glucose measurements.
\nDefining remission from diabetes as two consecutive measurements of a blood marker for high glucose, HbA1C, of under 6.5% at least 6 months apart, they looked at weight loss and remission over a period of an average 7.9 years. People with a body mass index (BMI) of under 15 or over 50 were excluded from the study.
\nThe research team found that just 6.1% of people enrolled in the study remained in remission from type 2 diabetes at the 8-year landmark.<\/p>\n
People who had lost 10% or more of total body weight in the year following diagnosis were over three times as likely to be in remission at the end of their follow-up compared to people who gained weight.
\nPeople who had lost between 5\u20139.9% of their body weight were over twice as likely as being in remission at the end of the follow-up compared to people who had gained weight.
\nThose who had lost up to 4.9% of their body weight had only a marginally better chance of being in remission than people who gained weight.<\/p>\n
Thus, while weight loss did contribute to the chance that an individual would see their type 2 diabetes go into remission, this was lower for people who had lost less weight.
\nEarly weight loss increases chance of diabetes remission
\nThe risk of redeveloping type 2 diabetes after remission was 48% lower for people who had lost over 10% of their body weight compared to people who had gained weight, and 22% and 10% lower for people who had lost 5\u20139.99% and less than 4.9% of their body weight, respectively.<\/p>\n
According to the authors, the study showed that while early weight loss did increase the chance of remission, achieving this in a real-world setting clearly came with challenges, as did maintaining remission.
\nDan Gallagher, a registered dietician at Aegle Nutrition, who was not involved in the study, was not surprised that the results of clinical trials have been hard to replicate in real-world settings.<\/p>\n
He told Medical News Today:
\n\u201cMany studies will provide a dietary intervention specifically for the study without any consideration for the sustainability of said diet. If the diet isn\u2019t easy to follow and doesn\u2019t completely change the potentially harmful (in reference to one\u2019s health) behaviors that caused the diabetes in the first place, then of course the patients aren\u2019t going to keep the weight off.\u201d
\n\u201cManaging type 2 diabetes is completely attainable through diet changes, but you have to continue these changes in perpetuity. It\u2019s not a 6-month change that will fix your blood sugar forever,\u201d he cautioned.<\/p>\n
\u201cIt\u2019s a complete lifestyle change that you make and stick with or the diabetes will return. This is the fact that many people either completely miss or don\u2019t understand when trying to change their diabetic status with diet,\u201d added Gallagher.
\nDr. Mir Ali, bariatric surgeon and medical director of MemorialCare Surgical Weight Loss Center at Orange Coast Medical Center in Fountain Valley, CA, who was also not involved in the research, advised MNT that \u201c[b]ariatric surgery, for those who meet the criteria, has the highest success rate for weight loss and long-term remission of many medical conditions.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
