In each study, conducted by the same team of researchers have compared the weight gain in patients treated with beta-blockers and witnesses who were not. In all, studies have focused on 11 468 subjects with hypertension or diabetes.
The results indicate that, compared to control groups, those taking beta-blockers - for an average of 5 years to 9 years, according to studies - consistently showed a higher weight. The difference between the 2 groups ranged from 5 kg to 20 kg and was still statistically significant.
Why beta-blockers do they grow?
In one study, conducted among 30 subjects, the authors measured 2 thermogenesis (heat saline) following a meal and physical activity level of subjects, whether or not treated with beta-blockers. The results indicate that patients treated, thermogenesis was reduced by half compared to that could be observed in others. Moreover, the activity level of subjects was 30% lower compared to untreated subjects.The researchers concluded that beta-blockers tend to reduce thermogenesis, causing a greater accumulation of fatty tissue, as well as increased oxidation of fat in the body. A reduced thermogenesis and increased oxidation of fat create more fatigue during exercise, explaining that the subjects treated with beta-blockers tend to exercise less.
According to researchers, patients who take beta-blockers in the long term should be more vigilant about theirweight by closely monitoring their diet and doing more of exercise . You can also ask his doctor to use another type of drug, or one of the beta-blockers for the latest generation, which would be less than the old antithermogéniques.
