Did you know that allergy medication (specificly anti histamines) can cause weight gain? Research done by Yale University in 05-06 followed a group of adults using antihistamines regularly (irrespective of brand) and found that compared to those who do not take antihistamines. The result? A difference in BMI (body mass index, personaly hate this metric) was different from 30 vs 28-29. This is not a large difference but the artical points out that there was no significant difference in fasting glucose, colesterol which are traditional markers of higher weight. The thing to note here is the BMI, the difference in observie weight was found to be 22 pounds in men and 10 pounds in women. Now this is not weight gained through the study, this is just the mean difference, not observed weight gain, they fail to provide this metric. If we presume they started in the same BMI, this would corrilate to an aproximate gain of 5-10 pounds in a year or so. So why is this? According to research antihistamines interfear with the "full" hormones in our diet, or at least block the reseptors in our brain to register that we are full leading to a potential of excess eating. Personally this reserch changed my appritch to allergy meds all together and i no longer take them as a whole, but take trace mineral instead. I still have decreased spring allergys and a noticable change in my hunger, though i wohld say i feel less urge to eat, i dont notice a change in my "desire" to eat. What do you guys think? Seem like medicin mumbo jumbo or a non repkrting from Big Pharma here in the US atleast?
