Does Anti-Anxiety Medication Cause Weight Gain?

Jump to Section

Anxiety disorders are the most common mental illnesses, affecting more than 40 million Americans. Anxiety, depression, personality disorders, bipolar disorder, and schizoaffective disorder all create a lasting effect on an individual’s mind, body, and well-being. Even though mental health medication can be helpful, it is beneficial to be mindful of reactions. There is a variety of different forms of anxiety medicine known to promote weight loss or weight gain along with numerous other side effects. 

Once the medication dispenses itself, it crosses the blood-brain barrier and regulates the operation of the GABAA receptor alpha-1 subunits. Once the neuronal activation reduces anti-anxiety medication activity in the central nervous system, negative results occur such as:

  • A heightening of appetite change
  • A shift in metabolic rate
  • Energy level fluctuation 
  • Body composition change
  • Cognitive impairment that lessens self-discipline 
  • Decreases the discretion of creating healthier meal plans 
  • Fatigue causes lower physical activity
  • Food cravings
  • Gastrointestinal reactions
  • Hormonal changes
  • Social eating
  • Taste alterations

How to Avoid Weight Gain on Anti-Anxiety Medications?

Track Medication and Diet

The majority of people who gain weight on anti-anxiety medications change their exercise patterns and track their caloric intake. If an individual isn’t tracking calories, it’s difficult to know whether or not the weight gain is a byproduct of the medication. The weight gain or weight loss that individuals that take anxiety medications experience can be a result of physical activity or calorie intake. By adjusting those two factors, weight gain should be counteracted.

Adjust Anti-Anxiety Medication Dose

Individuals that take anxiety medications should aim to receive the minimal effective dose possible. When anti-anxiety medication regulates physiology in ways that alter one’s weight, the dosage should be reduced to experience a less degree of weight change and psychological impact. 

Manage Side Effects

The majority of patients that take anti-anxiety medications will experience weight gain partially and fully due to side effects. An individual administering this medication could encounter constipation, bloating, fatigue, and as a result, weight gain. By referencing a doctor, effective treatments can assist with counteracting the side effects of this medication. 

Consider Alternative Options

If an individual is experiencing weight gain, it is important to scrutinize other supplements and medications that he or she is taking. Discontinuing the use of unnecessary supplements while taking anti-anxiety medication can greatly reduce the amount of weight gain being displayed. The other option is to ask a physician to prescribe one with medications or supplements that will assist in avoiding anti-anxiety medication weight gain. 

Longer-Term Anti-Anxiety Medication Administration

The biggest takeaway is the longer a body has time to adjust to a medication, the less intense the side effects will be. There is an adjustment period for the body to adapt to the regular presence of medication. It is recommended to attempt the journey of a new medication longer than possible to see if unwanted side effects will vanish as psychology gets acclimated.

Why Does Trazodone Cause Weight Gain?

Trazadone, also known as Desyrel is an approved medication used to treat depression. It functions as a serotonin antagonist and reuptake inhibitor. Trazadone obstructs the overabundance of serotonin at several receptor sites, along with hindering the reuptake of serotonin. The combination helps with not only depression but insomnia as well. 

In a recent clinical trial, individuals who took Trazadone for a continuous six weeks gained an average of 1.2 pounds. Though that isn’t a significant weight gain, patients who stayed on this medication for a longer period of time gained more weight. Trazadone is known for weight gain due to the people taking it experiencing an increase in appetite and sedative effects. 

Appetite Increase

When a person is depressed, it is more likely that he or she won’t have a big appetite for food. So once the individual begins taking Trazadone regularly, the realization that they need to eat comes back rapidly. The weight gain that occurs in individuals that start taking Trazadone can also be due to neurochemical altercations. 

Carbohydrates Cravings

Many patients claim that the Trazadone medication enhances carbohydrates cravings. Scientists have researched and found that there is a direct link between eating carbohydrates and serotonin production. So it is best to watch out for the carbohydrate intake. 

 Hormone Levels

Many individuals took Trazadone for an extended amount of time and experienced hormonal changes. Antidepressants are known for making it easier to gain weight. So though the change might be gradual, it is feasible.

What is Anxiety?

The main factor of anxiety is persistent, excessive worry, or fear in non-threatening situations. Anxiety is to be diagnosed by a physician who asks about medical history and performs a physical exam. The doctor will then refer the anxiety-ridden patient to a mental health professional if the individual is absent from physical illness. There will be various tests to look for physical illnesses since there are no specific lab tests to diagnose anxiety:

  • Being easily fatigued
  • Being irritable
  • Difficulty controlling feelings of worry
  • Having difficulty concentrating; mind going blank
  • Feeling restless, on-edge, and wound-up
  • Having sleep problems, such as difficultly falling or staying asleep, restlessness, or unsatisfying sleep
  • Having muscle tension 

What Are Some Anti-Medications for Anxiety?

There are numerous medications to assist with anxiety disorders. Two anxiety medications that cause weight gain are tricyclic antidepressants and atypical antidepressants. The anxiety medications that result in weight loss are SSRI’s also known as selective serotonin reuptake inhibitors and SRNI’s also known as serotonin and norepinephrine reuptake inhibitors. The issue is the two medications’ biggest side effect is nausea which results in loss of appetite, therefore, resulting in weight loss.
