Ketamine is a medical-approved injectable medication commonly used to relieve pain, induce a loss of consciousness, and treat depression. It is commonly referred to as a “dissociative anesthetic” as it helps one detach from pain. Ketamine is medically used to manage pain for burns, migraine, cancer pain, chronic neuropathic pain, and other types of chronic pain. Also, ketamine is used in mental care to treat depression, PTSD, anxiety, and anhedonia. 

Key Takeaways

  • Ketamine doesn’t directly induce weight loss but addresses underlying conditions like depression, which can lead to natural weight reduction.
  • Weekly ketamine injections can decrease appetite and slow down digestion, facilitating weight loss by reducing food intake.
  • While ketamine may assist in weight management, it should only be used under medical supervision due to potential risks and side effects.

Does Ketamine Cause Weight Loss?

One day of ketamine use has no effects on weight loss, however, repeated ketamine usage is said to have reduced weight. Ketamine does not cause weight loss directly but treats the underlying conditions, which leads to natural weight loss. It helps improve physical health and mental health while aiding in weight loss.

Ketamine Cause Weight Loss

Weekly injections helped people reduce appetite and food intake, which made weight loss easy. Also, it helps slow down digestion, which makes one feel fuller for longer. While ketamine acts as an easy weight loss solution that deprives one of suffering, it is not a safe way to lose weight as it has adverse side effects. This said ketamine is unsafe and dangerous to use without medical supervision. 

Fluctuations in weight may be caused by depression as it has an impact on physical health. Even though ketamine is not intended as a weight-loss aid, it helps with safe weight management. It triggers weight loss by balancing hormones and preventing fat storage and unhealthy cravings.

Most patients have reported experiencing weight changes during and after treatment, but it is not an ideal weight loss treatment. People with high BMI and obesity were associated with more responses to ketamine. Symptoms of depression include tiredness and having more cravings, which leads to weight gain. Ketamine helps eliminate the symptoms of depression, which helps lose weight easily. 

What Are The Other Benefits Of Ketamine?

  • Relieves chronic pain:

Ketamine has been widely used as an injectable medication to ease chronic pain. Health professionals use this method to relieve pain when painkillers are ineffective. Simply said, ketamine acts as an alternative to painkillers. Also, it is non-addictive and effective in treating migraines, neuropathic pain, and more. 

  • Treats depression and anxiety:

Ketamine is often used as a treatment for depression and anxiety. It is a more affordable alternative to antidepressants as one gets the treatment in small doses for an extended time. However, consulting a healthcare professional is necessary before starting this treatment. 

  • Improves insomnia:

Insomnia may be due to anxiety, mental stress, or depression. Ketamine has sedative properties and it helps one feel drowsy. It helps attain restful, uninterrupted sleep cycles quickly.

  • Restores balance in cortisol and stress levels:

Ketamine is highly effective against anxiety and depression as it helps bring balance between cortisol levels and emotions. It helps manage stress and have a more calm mind. 

Is Ketamine Safe?

Even though ketamine is said to be effective against depression, pain, and anxiety, it also has a high chance of causing health complications if we are not careful. However, ketamine is considered unsafe for pregnant women as it might cause pregnancy complications. It heightens the chance of birth defects in pregnant women. Also, people with heart conditions, high blood pressure, liver or kidney problems, and psychotic conditions should not use this medication.

Does Ketamine Cause Any Side Effects?

Ketamine may likely cause adverse side effects, too. Side effects do not occur in every case, but if they do, seek medical help.

The following side effects can be expected with ketamine use:

  • Dizziness
  • Irregular heartbeat
  • Blurred vision
  • Cough
  • Itching or skin rash
  • Sweating
  • Tiredness or feeling weak
  • Seizures
  • Swelling or puffiness of eyes or around the eyes
  • Bluish lips or skin

It cannot be said that ketamine directly enhances weight loss, but it helps with weight loss by treating the underlying cause. Often, treating depression, anxiety, and stress, ketamine treatment helps lose weight naturally. Ketamine is an injectable medication highly known to improve symptoms of depression over time. It also helps ease chronic pain, drug problems, and more. Usually, ketamine was used as an anesthetic, but it is now used to treat anxiety, PTSD, and other symptoms.

However, it cannot be asserted that ketamine is 100% safe. There is a high chance of getting side effects from using it. Ketamine treatment, without medical professional aid, might be dangerous. So, consult the doctor before opting for ketamine treatment.
