Can Antidepressants Therapy Lead To Weight Loss? Let’s Explore!

Did you know nearly 20% of people using antidepressants experience weight loss? Yes, your antidepressants can be the reason behind your unexpected weight loss.

Antidepressants are commonly used as medications for depression and other mental health illnesses. However, there is a category of these medications that can lead to weight loss.

In this blog, we will discuss these medications, their mechanisms, and what to do if you experience massive weight loss. Let’s discuss it!

What Are Antidepressants?

They are a category of medications that help reduce the symptoms of depression and other mental health disorders. Research on antidepressants in India suggests they primarily work on the neurotransmitters, which are responsible for regulating mood, emotions, and behavior.

Antidepressants are primarily used for the treatment of depression, anxiety, chronic pain, bipolar, and PTSD. 

Types Of Antidepressants And Their Mechanisms?

Antidepressants are categorized into different classes on the basis of their chemical structure and mechanism of action.

1. Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs are the most commonly prescribed antidepressants. As the name suggests, they work by blocking the reuptake of serotonin. This increases the levels of serotonin in the brain, which can help improve mood and reduce symptoms of depression.

2. Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

SNRIs have the same working mechanism as SSRIs. SNRIs inhibit the reuptake of norepinephrine. So, when the level of norepinephrine increases in the brain, it can reduce the symptoms of depression and anxiety. It also improves overall energy and concentration.

3. Tricyclic Antidepressants (TCAs)

It is an old group of antidepressants that is given to any patient when other medication fails. This is because TCA has a broad mechanism of action.

The mechanism of TCAs is to block the reuptake of serotonin and norepinephrine, similar to SNRIs. However, it also affects other neurotransmitters and receptors, which lead to a broader range of side effects too.

4. Monoamine Oxidase Inhibitors (MAOIs)

MAOIs inhibit the working of monoamine oxidase. This enzyme is responsible for breaking down neurotransmitters like serotonin, norepinephrine, and dopamine.

Blocking this enzyme, MAOIs increase the level of these neurotransmitters in the brain. They are also considered the last option for saving a patient because they have some reactions to foods and medication.

5. Atypical Antidepressants

This class of antidepressants includes a wide range of drugs that don’t fit neatly into any other category. Each atypical antidepressant has its own mechanism of action, which is tailor-made for the patients.

The general mechanism blocks the reuptake of neurotransmitters to increase their availability in the brain. Some drugs interact with various receptors in the brain, which can influence mood, anxiety, and other symptoms.

Impact Of Antidepressants On Weight

These drugs have varying effects on weight; they can increase or decrease your weight. We will mainly focus on how they lead to weight loss.

The impact of antidepressants on weight is highly individual. Those who are underweight can gain weight, while those who are overweight can lose weight. It all depends on how the medication is affecting their appetite and metabolism.

People with a faster metabolism are less likely to gain weight, and people with a slower metabolism are more prone to gain weight. On the other hand, your genetics also play a role in how your body will react to certain medications.

In the early stages of treatment, some antidepressants can lead to weight loss. This is because of the following reasons:

• They suppress your appetite.
• Increases the body’s energy expenditure
• Cause gastrointestinal side effects such as nausea, vomiting, and diarrhea.
• It can change the taste perception and reduce the pleasure that one gets from eating.
• These drugs reduce the chances of emotional eating.

Which Antidepressants Cause Weight Loss?

The mental health drugs that can cause weight loss are as follows:

• SSRIs such as fluoxetine can lead to weight loss. They decrease appetite and can cause nausea or gastrointestinal side effects. However, over time, it can lead to weight gain too. In a 2022 review, it was found that individuals taking 60 mg of fluoxetine experienced weight loss of 2.7 kg during the first 6 months of treatment.
  
• SNRIs such as venlafaxine and duloxetine can lead to weight loss as they increase energy levels and reduce appetite. However, these effects are different for each individual. In a 2006 review, it was found that duloxetine affects body weight. For short-term use, individuals lose weight, but for long-term use, it can lead to weight gain.
  
• Atypical antidepressants such as bupropion can cause weight loss. It reduces appetite and increases metabolism by affecting norepinephrine and dopamine levels. In a 2016 study, it was found that people who took bupropion lost weight on an average of 7.1 lb after 2 years of treatment.

How To Manage Weight With Antidepressants?

It will be difficult for you to manage your weight with antidepressants at some times. However, here are some effective ways to manage weight while you are on antidepressants:

• If you have concerns about weight gain or weight loss, then discuss them with your doctor, and they can give you the medications that will not cause weight gain or weight loss.
• Monitor your weight during a few months of starting the therapy, so if there are any changes to be made, your doctor can do that.
• Adopt a healthy diet practice. Include whole grains, lean protein, fruits, and plenty of veggies in your diet. At the same time, avoid processed foods and high-calorie foods, which can lead to unhealthy weight gain. Maintain an active lifestyle. Include more physical activity in your daily routine. You can opt for walking, jogging, swimming, or cycling.
• It is also essential to be mindful about your eating practices. So, eat slowly to allow your body to register when you are full, which can help you eat exactly how much your body needs.
• If your weight gain is significant and troubling you, then talk to your doctor about the possibility of adjusting the dosage or switching to a different medication.

Potential Risks And Considerations

When you are considering drug therapy for mood disorders, then it is important to consider the potential risks and side effects.

• The antidepressant drug’s side effects are nausea, fatigue, dizziness, dry mouth, and insomnia.
• SSRIs and SNRIs can cause sexual dysfunction. They can decrease libido, cause difficulty achieving orgasm, and cause erectile dysfunction.
• Tricyclic drugs can cause significant drowsiness, which impacts your daily functioning.
• The FDA has issued a black box warning for antidepressants as they can increase the risk of suicidal thoughts in patients under 25 years of age. This happens only in the initial days of treatment or when there is a change in the dosage.
• These drugs for mood disorders show withdrawal symptoms when someone abruptly stops taking them. So, to minimize withdrawal symptoms, it is important to reduce its intake slowly under your doctor’s guidance.
• If you are taking any other medication, it is important to know if they can interact with your antidepressant therapy. SSRIs and SNRIs can interact with pain medications or supplements and increase serotonin levels.
• This interaction can cause serotonin syndrome with symptoms like confusion, agitation, rapid heart rate, and increased body temperature. This can be problematic for people with hypertension.
• Long-term use of an antidepressant can make it difficult for the patient to discontinue them. It can also cause sexual dysfunction and weight gain. Long-term use of SSRIs can increase the risk of bone fractures in older adults.
