Does Prozac Cause Weight Gain – Prozac is among the most prescribed antidepressant. It belongs to the SSRIs class of medications, consisting of other products such as Lexapro, Paxil, and Zoloft.

Prozac has been used since the 1980s after Eli Lily pharmaceutical company, obtained permission to use the drug for treating depression, OCD, eating disorders and panic attacks.

Although ‘Prozac’ is just a brand name of Fluoxetine, it is the potent ingredient in SSRIs medicines. Like most drugs, several concerns have emerged due to the use of the drug. Most people ask; does Prozac cause weight gain?

Well, first, let’s look at how it works.

Fluoxetine in Prozac increases the levels of the body’s serotonin levels. The chemical is a stimulant thought to affect moods, appetite, and behavior.

If you have balanced serotonin levels, you will have a proper mental balance, and also, Prozac treats vomiting and binge-eating.

Prozac and Weight Gain

According to studies, SSRIs medications cause weight gain in only a quarter of the people. That means most of the users will not experience any weight effect.  On the other hand, the drugs can cause weight loss.

The weight changes are attributed to change in habits or behaviors and sometimes hormonal changes. A study published in the Cleveland Clinic Journal of Medicine noted that SSRI would cause weight changes after six months of use.

The “Drug Information Handbook” states that Prozac will cause weight gain in 1 in 10 patients.

Factors That Might Impact Weight Gain

Several factors have been blamed on weight changes. Firstly, the time span of use. For instance, if you the drug for small periods, let’s say several weeks the side effects will be negligible.

In the long term, two things happen. Patients may need to take even larger doses as the body builds resistance. With more dosage, the effects of weight gain may manifest.

Sometimes weight gain may result when patients use SSRIs and other medications together.

Likely Reasons Prozac Causes Weight Gain

The reasons suggested explaining why some patients experience weight gain includes:

Appetite Changes:
Prozac increase serotonin levels in the body. The hormone helps control your appetite. Most people who either binge-eat already have an eating problem.

Thus, Prozac corrects this condition. Inevitably, better appetite leads to weight gain.

Better Moods:
People respond in different ways to depression. Some may overeat also called stress eating. Others tend to eat very little and suffer as a consequence.

By correcting depression, those who had the condition, practice better-eating patterns.

Hormonal Changes:
SSRIs can further affect other hormones in the body. For instance, it may lead to reduced thyroid function resulting in the decreased production of cortisol, which is the body’s stress hormone.

This is thought to lead to slower metabolism thus fast weight gain. Some patients have claimed that they gained weight despite not eating more food. Well, a slow metabolism could explain the weight gain effect.

Verdict on Does Prozac Cause Weight Gain

Weight gain may hardly occur when you take Prozac. As you can see, there are several things at play. Also, only 25% of people may experience weight effects.
