Can anxiety and stress cause weight loss?

It is very difficult to live with anxiety without experiencing stress, and vice versa. They’re both holding hands. Both emotions can cause weight gain and loss. In this article, we’re going to answer this and other questions related to anxiety and weight, but first we tell you how anxiety and/or stress cause weight loss.

Lack of appetite

One of the most common symptoms, at the time you were diagnosed with anxiety or stress, is lack of appetite or no desire to eat. With less interest in eating, you eat fewer calories than your body needs. This lack of calories results in weight loss.

When you feel stress, you start to lose the urge to eat because of the amount of “things” and “noise” in your mind. You can see that you have hardly any appetite and when you start eating you feel like you’re getting satious very quickly. This happens to you and you don’t even realize it, because the word hunger doesn’t appear in your vocabulary. This causes you significant weight loss.

In addition to having no interest in food, anxiety and stress can simply make you forget to eat.

For example, what stresses you is a work situation, and you feel stressed by the uncertainty of whether or not you will finish a certain job on time, because it depends on whether you are renewed, or not, the contract. This will cause you to lose a lot of meals while trying to finish the job on time. The result of this results in weight loss.

You can easily adopt unhealthy eating habits. Even when you’re stressed try not to skip any food and try to make it as healthy as possible.

Nervous movements

One of the best known ways to lose weight is by exercising. Cardio is an example of exercise with which you lose a lot of weight. Walking or walking light is cardio.

But what does this have to do with anxiety or stress? Well, people who are living anxiously or stressed move restlessly,back and forth, and sometimes even restless those around. These movements cause a calorie burning similar to that performed in a cardio session, because of those constant movements


One of the most common medical recommendations when diagnosed with stress or anxiety is to perform some activity you like, exercise or sport.

If the activity you choose is to exercise or sport to generate more well-being to better control your emotions, you may notice weight loss.

Exercise is highly recommended for all people, especially those with anxiety or stress, as exercise causes you to generate the hormone of well-being. The hormone that makes you feel happier and therefore with a better mood.

Exercising can help you lose weight when this routine is incorporated as part of a comprehensive healthy weight loss plan. However, involuntary weight loss due to over-exercise anxiety or any of the other reasons listed here can put your health at risk.

Before you start exercising, we recommend that you consult with an expert.


Insomnia, little or nothing sleep, is one of the common symptoms of stress and anxiety. People who experience these emotions are often restless and have difficulty sleeping, ifthey sleep, it is not enough. When you have insomnia, your body doesn’t generate the right amounts of cortisol. It’s a stress-related hormone. The production of this hormone affects your metabolism. You have a faster metabolism and because you’re not eating, it results in weight loss.

Being awake longer, your body needs more energy than it would need if you had slept the recommended number of hours. This causes your body to look into its energy reserves to get the energy it needs, this can lead to weight loss.

Even if you’re stressed, your body needs rest and you should try to sleep. If you find it impossible to fall asleep by your means, you should consult your doctor. You can prescribe sleeping pills or other alternatives to get to sleep normally.

Don’t take over-the-counter medication pills, as it can be very harmful to your health and further aggravate symptoms of anxiety or stress.

Production of stress hormones.

When you have anxiety or stress, your body enters a state of struggle or flight. This state is also known as a response to acute stress, and is how your body responds to what causes stress or anxiety.

When you’re in this state, your body produces adrenaline and cortisol. Both hormones help you react and stay alert during stressful, dangerous, or unknown situations. The problem with these hormones is that they have side effects.

Adrenaline prepares your body for important physical activity as if you were running or fighting and this hormone also reduces your appetite. Adrenaline also causes faster heart rate and breathing, whichalso help burn more calories.

On the other hand, cortisol usually suppresses digestive, reproductive and immunological functions, among others. When your body digests less times, it means your body isn’t getting nutrients and those it has can throw them away as waste. This could also lead to weight loss, as not digesting food results in a calorie deficit.

Stress causes gastrointestinal discomfort

Stress and anxiety affect most parts of the gastrointestinal system. Causes symptoms such as:

Abdominal pain


Abdominal swelling

• Feeling nauseous and vomiting.


Reduced appetite



Pain when swallowing food.

All of these symptoms will affect you directly in your eating routines and therefore make you eat less. Causing weight loss.

Anxiety medications can lead to weight loss

If you’re experiencing severe anxiety, your doctor will most likely prescribe drug treatment to help you deal with it. Some of these medications have side effects that can cause weight loss.

Here are some of the medications and how they cause weight loss:

Benzodiazepines. This medicine acts as a central nervous system depressant. Side effects of this medicine include nausea, vomiting and upset stomach. These side effects can easily lead to weight loss.

Venlafaxine and Desvenlafaxine. These two medications are likely to cause you to lose your appetite and therefore cause weight loss.

• Buspirona. This medicine is known to cause many gastrointestinal side effects such as diarrhea, nausea, vomiting, stomach pain and others. These side effects can lead to weight loss.

Monoamine oxidase inhibitors. These medications also have gastrointestinal side effects, which can lead to weight loss.

Here are some examples of anxiety medications that can cause weight loss due to their side effects.

Can anxiety and stress cause weight GAIN?

Anxiety and stress can also cause weight gain. And here are some ways these two emotions can cause weight gain:

• Cravings for unhealthy foods. Some people crave foods like chocolates, pizza, chips and other unhealthy foods when they experience anxiety or stress. These are high-calorie foods and regular consumption of these foods is likely to cause weight gain.

Lack of sleep. Some people, when they can’t sleep, decide to eat at night. This can lead to weight gain. On the other hand, not as you don’t burn the calories you eat, as it’s night and your body is inactive, this often leads to weight gain.

• Reduced motivation to do anything. People who are stressed are tired most of the time. Lack of physical activity can lead to weight gain, as you’re just eating and lethargic without doing anything to help burn the calories you’ve consumed, resulting in weight gain.
