Vitamin D is a fat-soluble vitamin. Fat-soluble vitamins are stored in the body's fatty tissue. Vitamin D helps the body absorb calcium. Calcium and phosphate are two minerals that are essential for normal bone formation. Throughout childhood, your body uses these minerals to produce bones.

Vitamin D deficiency can lead to osteoporosis in adults or rickets in children.

Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. A spinal cord injury disrupts the signals. Spinal cord injuries usually begin with a blow that fractures or dislocates your vertebrae, the bone disks that make up your spine. Most injuries don't cut through your spinal cord. Instead, they cause damage when pieces of vertebrae tear into cord tissue or press down on the nerve parts that carry signals.

Dizziness is a term that is often used to describe two different symptoms: lightheadedness and vertigo. Light-headedness is a feeling like you might faint. Vertigo is a feeling that you are spinning or moving, or that the the world is spinning around you.

Psoriasis is a chronic autoimmune disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious. There are five types of psoriasis. The most common form, plaque psoriasis, appears as raised, red patches covered with a silvery white buildup of dead skin cells.

Pain signals keep firing in the nervous system for weeks, months, even years. There may have been an initial mishap -- sprained back, serious infection, or there may be an ongoing cause of pain -- arthritis, cancer, ear infection, but some people suffer chronic pain in the absence of any past injury or evidence of body damage. Many chronic pain conditions affect older adults.

Medical Radiation--X rays are a form of radiant energy like light or radio waves. Just like light and radio waves, they can pass easily through some things and are absorbed by others. In the human body, some tissues are better at absorbing the radiation than others. The images made by x-ray beams come from these differences. Bone stops x rays efficiently, making them look white in an image; air, like in the lungs, does not absorb radiation much at all, and looks black in the image. Sometimes the images are still, like pictures from a camera, and sometimes they show movement, like a video camera.

The pituitary gland is a pea-sized endocrine gland located at the base of the brain. The pituitary helps control the release of hormones from other endocrine glands, such as the thyroid and adrenal glands.

A pituitary gland tumor is an abnormal growth in the pituitary gland, the part of the brain that regulates the body's balance of hormones.

Pneumonia is an infection of the lungs that is usually caused by bacteria or viruses. Globally, pneumonia causes more deaths than any other infectious disease.

Grief is a reaction to a major loss. It is most often an unhappy and painful emotion. Grief may be triggered by the death of a loved one.

Lyme disease is a bacterial infection you get from the bite of an infected tick. The first symptom is usually a rash, which may look like a bull's eye (although some people never get the tell-tale bullseye rash).

Shingles is caused by the varicella zoster virus, the same virus that causes chickenpox. After a person recovers from chickenpox, the virus stays in the body in a dormant (inactive) state. For reasons that are not fully known, the virus can reactivate years later, causing shingles. Almost 1 out of every 3 people in the United States will develop shingles, also known as zoster or herpes zoster. There are an estimated 1 million cases each year in this country. Anyone who has recovered from chickenpox may develop shingles; even children can get shingles. However the risk of disease increases as a person gets older. About half of all cases occur among men and women 60 years old or older.

Amyotrophic lateral sclerosis (ALS),sometimes called Lou Gehrig's disease, is a rapidly progressive, invariably fatal neurological disease that attacks the nerve cells (neurons) responsible for controlling voluntary muscles. The disease belongs to a group of disorders known as motor neuron diseases, which are characterized by the gradual degeneration and death of motor neurons.

Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder, meaning it is a problem caused by changes in how the GI tract works. People with a functional GI disorder have frequent symptoms, but the GI tract does not become damaged. IBS is not a disease; it is a group of symptoms that occur together. The most common symptoms of irritable bowel syndrome are abdominal pain or discomfort, often reported as cramping, along with diarrhea, constipation, or both. In the past, irritable bowel syndrome was called colitis, mucous colitis, spastic colon, nervous colon, and spastic bowel. The name was changed to reflect the understanding that the disorder has both physical and mental causes and is not a product of a person's imagination.

Vitamin D toxicity, also called hypervitaminosis D, is a rare but potentially serious condition that occurs when you have excessive amounts of vitamin D in your body. Vitamin D toxicity is usually caused by megadoses of vitamin D supplements — not by diet or sun exposure.
