What Heroin Does To Your Body

Over time, your body develops a tolerance to heroin. This means that, in a way, your brain has been rewired to feel “normal” when heroin is present. Your body has adjusted to the heroin and the dopamine that’s present so you don’t feel a high anymore, even right after taking heroin. You need to take larger doses to feel anything. One way to tell that your body has developed a tolerance to heroin is when you don’t take it, you feel abnormal.

When you’re a long-time user of heroin, it ultimately changes the structure and the physiology of your brain. The impacts on your hormone systems are difficult to reverse. There is also some research showing heroin use can cause a decline in the white matter of your brain, causing a range of cognitive, memory and decision-making problems.

Physical dependence on heroin can lead to withdrawal symptoms if you stop using it. These symptoms can range from flu-like symptoms to severe pain, insomnia and gastrointestinal issues.

• Pain and anxiety relief
• Flushing of the skin
• Feeling that your arms and legs are heavy
• Increased body temperature
• Nausea and vomiting
• Dry mouth
• Extreme itching
• Going in and out of consciousness
• Slowed heart rate or irregular heart rate
• Slowed breathing

What heroin does to your body can ultimately be what leads to a deadly overdose.

Some of the ways heroin can damage your body include:

• It can cause your brain to not receive enough blood
• Your respiratory system can shut down so you can’t breathe
• It can lead to something called infectious endocarditis on the surface of the heart, which is caused by injecting heroin and can result in heart failure
• Kidney failure can occur

• Oral health problems including damaged teeth and swelling of the gums
• Skin problems from scratching
• Extreme constipation
• A weakened immune system
• Malnutrition
• Sleep problems
• Problems with sexual functioning

Along with the ways heroin impacts your body in the long-term, there can be even more dangerous ways it can destroy your overall health. This includes organ damage to the liver and kidneys from infectious diseases (from needle sharing and injection) and brain damage from a lack of oxygen that occurs during overdoses.

People who inject heroin also report having health issues including infections of the heart valves, bacterial infections and abscesses. Chronic heroin users often have lung problems, including the development of tuberculosis and pneumonia; women have irregular menstrual cycles, or they stop altogether; and people who snort heroin have damage to their mucosal tissue.

If you inject heroin, it can lead to scarred and collapsed veins, blood infections and soft tissue infections. Tissue in your vital organs may be damaged or destroyed, and because of immune reactions to contaminants often found in heroin, it can lead to arthritis and other similar problems.
