Illustration of alcohol effects on health.

Alcohol has an effect on almost every body organ in the short and long term. Their effect depends on its amount and duration of drinking. Alcohol causes numerous problems in the body, but it also provides a lot of energy because it is energy-rich. They affect many organs. Here we are discussing. Alcohol can disrupt transactions in the brain between nerve cells, causing short-term and long-term memory difficulties, mood disorders, and cognitive decline. The heart and circulatory system are also crucial organs at risk from excess alcohol. Chronic alcohol use can cause high blood pressure, cause the heart muscle to weaken (alcoholic cardiomyopathy), and increase the chances of stroke. Native to the skeletal system and muscles weakened from alcohol, it is known that alcohol makes bones less dense, leads to weakened muscles, and delays recovery from injury. Hormones related to alcohol also greatly discourage healthy bones and muscles.

This is followed by muscle weakness, decreased strength in chronic alcohol use, muscles will waste away and become weak, a condition known as alcoholic myopathy. Athletes and those who exercise on a regular basis may find that they, too, will have delayed recovery after exercising in the hours following because alcohol increases inflammation and interferes with the body’s ability to heal process.

It disrupts hormone levels; for men, that means lower testosterone, and for women, it affects their estrogen levels as well. Decreasing hormones will decrease bone density. Decreased bone density is inhibitive in the healing process, as after fracturing bone or injuries, the healing process will decrease rapidly. All of this, alongside the fact that alcohol impairs coordination and reflexes, makes falls and fractures significantly higher risks for very heavy drinkers.

  • Temporary muscle weakness and poor coordination occur.
  • Long-term use loss of muscle mass and a reduction in its strength.
  • Increase the risk of osteoporosis.
