Anxiety is a natural response of the body to stressful situations, but when it becomes chronic, it can affect health in multiple ways. One of the less discussed but significant effects is unintentional weight loss. In this article, we explore why anxiety can cause weight loss, the associated symptoms, and strategies for getting back into a healthy routine.

Why can anxiety cause weight loss?

When a person experiences prolonged anxiety, the body enters a state of constant alert. This activates the sympathetic nervous system, which releases hormones such as cortisol and adrenaline. These substances can:

  • Reduce the feeling of hunger by altering the levels of ghrelin and leptin, hormones responsible for appetite.

  • Affect the digestive system, generating problems with nutrient absorption.

  • Accelerate metabolism, increasing energy expenditure even at rest.

  • Cause insomnia or sleep disturbances, affecting the body's regeneration.

While in some cases this weight loss is mild, in situations of severe or prolonged anxiety it can lead to nutritional deficiencies that affect overall health.

Symptoms of weight loss due to anxiety

Anxiety-related weight loss is often accompanied by a number of symptoms that can help identify its cause:

1. Lack of appetite and reduced desire to eat

Constant worry and stress can suppress appetite, causing people to go long periods without eating or to experience food aversions.

2. Digestive problems and poor absorption of nutrients

Anxiety affects the digestive system, causing symptoms such as nausea, abdominal pain, diarrhea, or constipation. It can also lead to an imbalance in the gut microbiota, affecting the absorption of essential vitamins and minerals.

3. Acceleration of metabolism and increase in caloric expenditure

Constant alertness causes the body to expend more energy, which can lead to weight loss even without changes in diet or physical activity.

4. Weakness, fatigue and loss of muscle mass

The combination of poor nutrition, high caloric expenditure, and lack of rest can lead to a constant feeling of exhaustion and, in some cases, loss of muscle mass.

5. Changes in sleep and hormonal balance

Insomnia and sleep disorders are common in people with anxiety, which can impact hormonal balance, influencing metabolism and the body's ability to maintain a stable weight.

How to differentiate weight loss due to anxiety from other disorders?

It is important to differentiate whether weight loss is related to anxiety or if it could be due to other medical conditions, such as:

  • Hormonal problems, such as hyperthyroidism.

  • Gastrointestinal diseases, such as irritable bowel syndrome.

  • Eating disorders, such as anorexia nervosa.

  • Chronic diseases that affect nutrient absorption.

If weight loss is significant or accompanied by symptoms such as fever, persistent pain, or extreme energy changes, it is advisable to see a specialist to rule out other underlying causes.

Effective strategies to get back into a healthy routine

If anxiety is affecting your weight, it's essential to implement lifestyle changes that help regulate stress and improve nutrition.

1. Conscious and balanced diet

  • Eat at regular times, even if you don't feel hungry.

  • Prioritize foods rich in protein, healthy fats, and complex carbohydrates.

  • Avoid excessive consumption of caffeine and ultra-processed foods, which can increase anxiety.

2. Relaxation and stress management techniques

  • Practice deep breathing exercises and meditation.

  • Include relaxing activities in your daily routine, such as listening to music or reading.

  • Prioritize rest and maintain proper sleep hygiene.

3. Adequate physical exercise

  • Engage in moderate physical activity, such as yoga, walking, or strength training.

  • Avoid excessive intense cardio, as it can increase cortisol release.

  • Find sports or activities that promote relaxation and well-being.

4. Professional support: psychologists and nutritionists

  • A mental health specialist can help manage anxiety with cognitive-behavioral therapy.

  • A nutritionist can design a meal plan that helps you regain a healthy weight without creating additional stress.

Conclusion

Weight loss due to anxiety is a reality many people face, but with the right approach, it's possible to regain balance. The key is to identify the warning signs, differentiate this situation from other disorders, and adopt effective strategies to improve overall well-being.

Additionally, complementing these habits with the support of specific products can contribute to stress management and energy recovery. Pleniage Pro Calm , with natural ingredients like Ashwagandha and GABA, can help safely reduce anxiety. Pleniage Energy Pro, on the other hand, is formulated to combat fatigue and improve vitality during periods of high stress. Incorporating these supplements into a healthy routine can make a significant difference in daily well-being.
