2. Abnormal Digestive & Endocrine Gland Activity

Too much alcohol can lead to abnormal digestive and endocrine gland activity. This means the pancreas gets blocked up with enzymes the lead to inflammation which then leads to pancreatitis. This is a long-term condition that has causes serious health problems.

3. Decrease Blood Sugar Levels

The pancreas works to help the body regulate blood sugar levels, insulin and responds to glucose. When the pancreas doesn’t function properly it can cause a drop in blood sugar levels. Additionally, pancreas damage prevents the body from creating insulin to use the sugar.

If our bodies can’t manage the blood sugar levels, it can lead to diabetes or hypoglycemia. 

4. Central Nervous System Damage

Alcohol effects our central nervous system by reducing the communication between the body and brain. This affects speech, balance and can cause numbness and tingling sensations in hands and feet. This type of impairment is what leads to drunk driving accidents, memory loss and reduces our ability to make rational choices.

Additionally, over time, the effects of alcohol damage our frontal lobe which is responsible for emotional control, short-term memory, judgement and impulsivity. Chronic use of alcohol can lead to mental illness and brain disorders like Wernicke-Korsakoff syndrome.

11. Reduces Body’s Natural Immune System

12. Malnutrition

Frequent drinking can lead to malnutrition because alcohol becomes a replacement for other types of nutrients. Not only does it not contain any health carbohydrates, proteins, minerals or vitamins, it actually inhibits the absorption of these vital nutrients. 

13. Birth Defects

People who drink while pregnant can expect the babies to be born with birth defects, premature delivery, miscarriage or stillbirths. Additionally, drinking during pregnancy puts the unborn baby at risk of Fetal Alcohol Syndrome and other serious problems.

14. Blackouts

A lot of regular drinkers can attest to experiencing blackouts. These are gaps in memories that happened while the person was intoxicated. Alcohol temporarily blocks the transfer of memories from short-term to long-term storage. It is commonly referred to as memory consolidation and takes place in the area of the brain called the hippocampus.

15. Hallucinations

Drinking too much alcohol can cause temporary psychosis that includes experiencing hallucinations. Hallucinations can also be a severe symptom of alcohol withdrawal.

16. Shrinking Brain

The effects alcohol has on the brain can cause the brain to shrink and become deficient in white matter. These white matter fibers are what carry information between brain cells. It can lead to daily mental, emotional and physical dysfunction.

17. Fatigue

Drinking alcohol reduces the part of the sleep cycle known as Rapid Eye Movement (REM). Loosing this part of the sleep cycle leads to fatigue, low energy, drowsiness and a decrease in concentration.

18. Tooth Decay

The high sugar content and acidity in alcohol can cause the enamel in our teeth to breakdown. The enamel is what prevents cavities, decay and mouth diseases. Additionally, people who are drunk may forget to brush their teeth as often as they need to.
