causes:
Hepatitis A: eating infected food or IV drug abuse
Hepatitis B: mother gave it to you at birth (most common in world), Sexual transmission (most common in US), IV drug abuse, including cocaine
Hepatitis C: IV drug abuse, including inhalational drugs like cocaine (even 1 time) accounts for 90%, also transfusions prior to 1994. Tattoos and body piercing also risk factors, but rarely.
Drinking coffee is not a risk factor (thankfully)

Causes
The liver is not only the largest internal organ in your body, it's also one of the hardest working and most complex. It performs hundreds of vital functions, including processing most nutrients, producing bile and blood-clotting factors, and removing drugs, alcohol and other harmful substances from your bloodstream. Because the constant exposure to a multitude of toxins can damage the liver and lead to hepatitis, many cases of hepatitis are alcohol or drug related.
But in autoimmune hepatitis, the threat is much closer to home. The body's immune system, which ordinarily attacks viruses, bacteria and other pathogens, instead targets the liver, leading to chronic inflammation and increasingly serious damage to liver cells. Just why the body turns against itself is unclear, but autoimmune hepatitis appears to be triggered by:
* Infections. Autoimmune hepatitis can develop after a viral infection such as acute hepatitis A, hepatitis B, measles or Epstein-Barr virus infection. Epstein-Barr is one of the most common human viruses and linked to a number of disorders, including mononucleosis.
* Certain drugs. Some medications injure the liver directly — overdoses of the common pain reliever acetaminophen (Tylenol, others), for example, can cause liver failure. Other drugs harm the liver indirectly by stimulating an abnormal immune response that then harms liver cells. These drugs include interferon, which is commonly used to treat cancer, the high blood pressure medication methyldopa/hydrochlorothiazide (Aldoril), antibiotics such as minocycline — often used to treat adolescent acne — and nitrofurantoin, the anti-inflammatory diclofenac, and possibly the cholesterol drug atorvastatin (Lipitor).
* Genetic abnormalities. Some people seem genetically predisposed to develop autoimmune hepatitis. Researchers have identified certain gene deletions that increase the likelihood the disease will develop at a young age. Other genetic abnormalities may make autoimmune hepatitis more aggressive and harder to treat.
Types of autoimmune hepatitis
Doctors have identified two main forms of autoimmune hepatitis:
* Type 1 (classic) autoimmune hepatitis. Often developing suddenly, this is the most common type of the disease. Although it can occur in anyone at any age, most of those affected are young women. About half the people with type 1 autoimmune hepatitis have other autoimmune disorders such as thyroiditis, rheumatoid arthritis or ulcerative colitis. Their blood is also likely to contain antibodies against organ tissue.
* Type 2 autoimmune hepatitis. Although adults can develop type 2 autoimmune hepatitis, it's most common in young girls and often occurs with other autoimmune problems. Researchers once thought that type 2 autoimmune hepatitis was more difficult to treat than type 1 is, but it now appears that both respond equally well to steroid therapy.
NO IT'S NOT TRUE.

There are many things that cause hepatitis, but they are things like viruses, toxic substances and other diseases. I think your mom told you that so you would shower before breakfast.
