Weight Loss Medications: Do they work?

Pill Bottles and PillsPill Bottles and Pills

I recently had a request to write and article one weight loss medications.   As a physician, I try everything in my arsenal to avoid having to go this route with patients.  I would prefer that they not have to take medications, but some are not able to lose weight without them.  My personal opinion is ……

Ok, I prescribe weight loss medications.  They are not a magic bullet that will let you lose weight fast without diet and exercise.  Even with this medication, you must watch what you eat and exercise.  With our a multi-prong approach, you will not lose weight or even if you do happen to lose a few pounds, you will gain it back one you stop the medication because you failed to change the behavior that cause the weight gain.  If your weight gain is because you are sedentary and over eat, unless you change the behavior, the risk of the medication is not worth the benefit.  

Most of my patients are not authorized to take them but their families are.  I personally think that they should rarely be used for weight loss.  Most of the patient that have asked me to prescribe them have not done their due diligence to try to loose weight without them.  They want a quick fix and I refuse to write a prescription in that group.

When do I write for them?  I am not a weight loss specialist, but I have ample experience helping patients lose weight.  I usually require them to do several steps before I am willing to consider a medication:

  1. Some provider start weight loss medication at a BMI of 27.  I do not not consider them until 30.  
  2. The patient must have labs that are normal lab tests.  Endocrinology causes are the minority, but they are quick win when you find them.
  3. I will review their medical history to ensure that do not have a history of an eating disorder.  
  4. Patients must see a Dietician to review their diets.
  5. Patients must see a Trainer and try at least 6 weeks of diet and exercise without successful weight loss.  
  6. All patients are referred to behavioral health provider to ensure there is not a BH condition hampering their ability to lose weight.

Remember, more is not better.  A handful is dangerous so take them as prescribed.  All of the medication are addictive or have potentially fatal side effects.  I would never take them lightly.  Do not mix any other weight loss supplements with them.  

Do they work?  The bottom line is that they do work to help with weight loss, but the do not work to cause long term weight loss maintenance.  Most studies show that in the long term, patient regain the weight.  You absolutely must learn to eat healthy so if you plan to keep it off, you might be better off just learning to eat and exercise correctly.
