SSRIs (Selective Serotonin Reuptake Inhibitors) have become more popular in the past 10 to 15 years as anti-depressants because of their minimal side effects compared to older anti-depressants. This does not mean there are no side effects, nor does it mean the side effects associated with SSRIs cannot become incredibly serious. One of the more common and worrisome side effects of taking an SSRI is weight gain.

Why Does SSRI Cause Weight Gain

It is currently not understood exactly why SSRIs cause weight gain in many patients. All the information that is available only shows a correlation between SSRIs and weight gain based upon studies performed that show many, though not all, individuals who begin taking a SSRI also gain weight.

It is not known why, but SSRIs lower your body's metabolism. This means that your body begins to burn less calories per hour throughout the day and at night during sleep. So if you are not overeating, you can still gain weight. Cutting calories will only help so much in this instance depending upon how low your metabolism drops.

Some scientists attribute much of the weight gain phenomenon to the SSRI helping the individual overcome depression. As the patient begins to feel better and becomes better able to deal with his or her depression, the appetite returns. This, of course, can result in weight gain, as many who suffer depression lose weight and stop eating regularly.

There are several different SSRIs on the market and they are somewhat different based upon the chemicals that are used in the make up of the anti-depressant. Of the most popular brands, Paxil has been shown to cause the most weight gain in the most subjects. The other brands have also shown to increase the weight of those who take the drugs on the average of 15 to 20 pounds over a prolonged period of time. Again, the correlation of SSRIs and weight gain is less than that of the previous anti-depressant alternatives of the past such as TCAs and MAOIs.

What to Do About Weight Gain and SSRI

Because you may be gaining weight due to a decrease in metabolism, your options are rather limited, but there are some healthy alternatives to simply gaining the weight.

• Begin an exercise regimen
• Reduce overall calories per day
• Stay away from charcoal grilled foods

 
The charcoal grilled foods can block your metabolism and further your problem. If you have cut your fat and calorie intake, started an appropriate exercise regimen and cut your intake of charcoal grilled foods and are still gaining weight, you need to consult your physician.

Your doctor can help you to define precisely why you may be gaining and may change your dosage or switch you to a different SSRI. Article Source: http://EzineArticles.com/?expert=Robert_McKnight
