Restless legs syndrome (RLS) also known as Willis-Ekbom disease (WED) or Wittmaack-Ekbom syndrome, is a neurological disorder characterized by an irresistible urge to move one’s body to stop uncomfortable or odd sensations.
It most commonly affects the legs, but can affect the arms, torso, head, and even phantom limbs. Moving the affected body part modulates the sensations, providing temporary relief.

Breast cancer does not show any symptoms in the initial stages. Formation of lumps and cysts in the breasts are quite common and most of them are benign in nature.
But these lumps, cysts or fibroids can turn cancerous depending on the individual. One should go for various screening tests of breast cancer if certain changes are observed in the breast.
1. Formation of lumps or hardening around the breast or in the under arms.
2. Any change in the shape and size of the breast.
3. Crumpling of the breast skin.

A kidney stone, also known as a renal calculus is a crystal aggregation formed in the kidneys from dietary minerals in the urine.
Urinary stones are typically classified by their location in the kidney (nephrolithiasis), ureter (ureterolithiasis), or bladder (cystolithiasis), or by their chemical composition (calcium-containing, struvite, uric acid, or other compounds).
Kidney stones typically leave the body by passage in the urine stream, and many stones are formed and passed without causing symptoms.

Brain cancer is one of the most dangerous because nearly all tumors that arise in the brain are malignant.
Although it is less likely that a primary tumor in the brain will metastasize and spread to other parts of the body, the brain is such a sensitive and vital organ that surgery is usually very dangerous or impossible.
Brain cancer is also harder to treat than other types of cancer because of the blood-brain barrier that doesn’t allow many types of drugs to pass into the brain.

Gastric bypass surgery refers to a surgical procedure in which the stomach is divided into a small upper pouch and a much larger lower “remnant” pouch and then the small intestine is rearranged to connect to both.
Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass (GBP) procedures. Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
The operation is prescribed to treat morbid obesity (defined as a body mass index greater than 40), type 2 diabetes, hypertension, sleep apnea, and other comorbid conditions.

Bladder cancer is a condition where cancer cells have spread beyond the bladder due to the exposure to chemicals and other substances.
What is the bladder and where is it located?
The urinary bladder is an organ that collects and holds the urine after the kidneys have filtered it. The urinary bladder is just above and behind the pubic bone; an empty bladder is about the size and shape of a pear.
Common diseases in the bladder
There are a variety of causes that may result in bladder dysfunction; such causes may result in the following diseases:

Cholesterol is an organic molecule. It is a sterol (or modified steroid), a lipid molecule and is biosynthesized by all animal cells because it is an essential structural component of animal cell membranes that is required to maintain both membrane structural integrity and fluidity.
Cholesterol enables animal cells to:
(a) not need a cell wall (like plants & bacteria) to protect membrane integrity/cell-viability and thus be to change shape
(b) move about (unlike bacteria and plant cells which are restricted by their cell walls).

Cancer is a disease that affects cells of the body. Cells are extremely small units that build together and form all living things, which include human beings.
In any given person’s body, you will find billions of cells.
Cancer occurs when unusual and abnormal cells grow and spread very quickly. Normal cells in the body divide, grow to a certain size and then stop. Over the course of time, cells will even die.
Cancer cells do not follow this normal pattern of division and growth. They divide very quickly and just continue to grow.

An allergy is a hypersensitivity disorder of the immune system.
Symptoms include: red eyes, itchiness, and runny nose, eczema, hives, or an asthma attack.
Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening reactions called anaphylaxis.
Food allergies, and reactions to the venom of stinging insects such as wasps and bees are more often associated with these severe reactions. Not all reactions or intolerances are forms of allergy.

Keeping the lungs healthy means keeping them free from pollutants, irritants and anything else that might damage them. The lungs function best when they are filled with clean air, which is rich in oxygen and free from harmful gases, chemicals, or dust particles.
The most important aspect to keeping the lungs healthy is to avoid smoking. If you are already a smoker, ask your doctor for help to quit. Cigarette smoke contains over 4,000 different chemicals, at least 500 of which contribute to the formation of cancer.
