Hepatitis A signs and symptoms, which typically don't appear until you've had the virus for a few weeks, may include: Fatigue Nausea and vomiting Abdominal pain or discomfort, especially in the area of your liver on your right side beneath your lower ribs Clay-colored bowel movements Loss of appetite Low-grade fever Dark urine Joint pain Yellowing of the skin and eyes (jaundice) If you have hepatitis A, you may have a mild illness that lasts a few weeks or a severe illness that lasts several months. Not everyone with hepatitis A develops signs or symptoms.

The hepatitis A virus, which causes the infection, usually is spread when a person ingests even tiny amounts of contaminated fecal matter. The hepatitis A virus infects liver cells and causes inflammation. The inflammation can impair liver function and cause other signs and symptoms of hepatitis A. Hepatitis A virus can be transmitted several ways, such as: Eating food handled by someone with the virus who doesn't thoroughly wash his or her hands after using the toilet Drinking contaminated water Eating raw shellfish from water polluted with sewage Being in close contact with a person who's infected — even if that person has no signs or symptoms Having sex with someone who has the virus

Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%–6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.

Hepatitis E is a virus that can infect the liver. Unlike other forms of hepatitis, the hepatitis E virus usually doesn't lead to long-term illness or serious liver damage. Most people get well within a few months.

Occupational respiratory disease is any lung condition you get at work. Certain workplaces lend themselves to disease. The most common are coalmines and factories or areas with high amounts of toxins. These include asbestos and silica dust, as well as smoke, fumes, gases, and other particles.

It also includes forms of asthma, bronchitis, or emphysema.

Your lungs are have 600 million air pockets -- enough to cover a tennis court.

A giant abdominal wall hernia can develop from an existing ventral or incisional hernia, sometimes arising after one or more failed repair attempts. These hernias may also result from a traumatic injury where the abdomen was required to be left open and healing was delayed. In giant abdominal wall hernias, multiple loops of intestines and sometimes other abdominal organs reside within the hernia sac. The abdominal wall muscles then become conditioned to this and retract reducing the available space inside the abdomen.

Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing. White blood cells are sent to attack the infection, which causes tissue at the site of the infection to die. This creates a small, hollow area that fills with pus (an abscess).

The cyst was technically 46.5 pounds and her doctors call it the largest in world history. I am not sure if that is true, but it is a massive cyst

Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.

Laser tattoo removal is simple, safe, and produces fantastic...

Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.

Most minor cuts you can treat yourself -- but know when to see a doctor:

Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm inside a woman's uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization

Most C-sections are done under regional anesthesia, which numbs only the lower part of your body — allowing you to remain awake during the procedure. A common choice is a spinal block, in which pain medication is injected directly into the sac surrounding your spinal cord
