How Does Heroin Impact Weight?

Ongoing heroin use can contribute to a number of negative health problems, including weight loss. 

In the short term, people using heroin may be neglecting to eat healthily or even at all, which can lead to acute dehydration or electrolyte imbalances. In addition, heroin exerts its influence on the GI tract, often leading to constipation, nausea and vomiting which can in turn cause decreased appetite and weight loss. [ 2] In some cases, constipation can be so extreme it can lead to GI tract obstruction, which can be life threatening and require hospitalization or surgery.[3] 

Long term, people who are not eating due to drug use can lose weight and eventually even muscle mass, leading to chronic malnutrition. [1] Rapid and extreme weight loss can lead to the following complications: 

  • Electrolyte imbalances: In heroine users, electrolyte imbalances as a result of dehydration and malnutrition can lead to cardiac arrhythmias and even death. 
  • Vitamin Deficiencies: Weight loss and chronic malnutrition in patients with heroin use can cause vitamin deficiencies that lead to a number of other complications such as increased risk of bleeding, bone mineral density loss, etc. 
  • Muscle loss (Sarcopenia): Muscle loss can lead to fatigue, deconditioning, increased risk of falls and injury 
  • Mental and emotional co-morbidities: Rapid weight loss can lead to abnormal hormonal regulation, including decreased dopamine and serotonin, both of which are necessary for normal mood regulation. Consequently, malnourished patients can experience mood changes, depression, anxiety, and other mental health conditions.
