Antidepressants and Weight Gain
If you're taking an antidepressant, you're not alone. The use of antidepressant medications has grown by nearly 400% over the past 20 years. According to the National Center for Health Statistics (NCHS), approximately 1 in 10 Americans are currently taking some form of medication to deal with depression.
That's profitable news for the people making the pills, but the side effects may be causing problems for patients. Up to 25% of people taking antidepressant medications may see a weight gain of 10 pounds or more.
To be fair, in some the weight gain may not be caused by the medication, but simply a change in mood. Depression can make food unappetizing or cause people to lose interest in eating. Weight loss follows. If depression is lifted, the appetite often returns.
It's when the side effects do more than return you to normal that problems happen. Some studies show antidepressants can increase cravings for food, particularly carbohydrates. Unless that craving can be quenched, unhealthy weight gain can appear as soon as six months after starting the drug. It's also possible some antidepressants can lower your metabolism. Then, even if your eating habits stay consistent, weight gain happens because your metabolism isn't burning off as many calories every day.
There are several things you can do. The first is to remember the bigger picture. Don't stop, change or start a new drug without going over the options with your doctor first. If you're taking an antidepressant medication, your prescribing doctor believes the benefit it provides outweigh the potential side effects. Consider the long-term pros and cons of therapy for your overall well-being.
Have your doctor weigh you. Your physician will take your concerns much more seriously if there is clear documentation of how much weight gain has occurred over time. That's especially true if the weight readings are done in the doctor's office and kept in your medical file.
Track your food. Unless you start to honestly record how many calories you're taking in daily, it's unlikely you'll ever change. That's OK if you're happy with being overweight or obese, but don't pretend it's all the fault of the medicine if you're not willing to record things.
Track your mood. In 2009 I wrote an article about your emotions (Exercise Your Blues Away) and posted a "Mood and Exercise Chart." I've attached the chart below so you can print it out and track your emotions daily. Bring those records to your doctor when you go for follow-up visits. Charting your feelings can give clues to possible causes and triggers as well as options for additional treatment.
Schedule an appointment with a mental health professional. One of the most surprising statistics about people on antidepressant drugs is that less than a third of Americans taking them have seen a mental health professional in the past year. That would be like being diagnosed with cancer, starting a cancer treatment and staying on the cancer drugs without ever going back to the doctor to see if it's working. You may not need the medication, you may need to alter your prescription or you may need to add something to your program.
Get up and do something physical. Schedule something with a trainer, a friend, a group fitness class or simply go out in the world and start moving. Don't set any grand goals; just try to make getting up and being active for 30 minutes a daily habit.
Some antidepressant drugs are more prone to causing weight loss than others. Do not use that list to self-prescribe what may work for you merely to be aware of the effects if you’re on those medications.
