Stretch mark facts
What are stretch marks?
Stretch marks appear as linear streaks on the skin that has been overstretched, and they run perpendicular to maximum lines of tension in the skin. They begin as flat red lines, and over time they appear as slightly depressed white streaks. They tend to occur near the armpits, on the thighs, abdomen, chest, and groin. Their appearance is similar to changes seen in the surface of rubber balloons that have been overinflated.
What causes stretch marks?
There is some controversy over the precise mechanism by which striae occur. There seems to be damage to the elastic fibers of the dermis (the deeper layer of the skin) accompanied by inflammation which eventually results in scar-like changes. These changes appear to be induced by excessive physical stretching of the skin. There are a number of clinical situations which will predispose the skin to the formation of striae. These include rapid and excessive increase in body mass, the excessive use of topical or systemic glucocorticoid drugs (steroids), Cushing's disease (overproduction of glucocorticoids by the adrenal gland), puberty, Marfan's syndrome and Ehlers-Danlos syndrome (two uncommon genetic diseases), excessively large breast implants, and pregnancy.

What are risk factors for stretch marks?
Excessive rapid weight gain and pregnancy are the two most common risk factors. Other risk factors include the conditions described above that predispose the skin to developing stretch marks.
What are symptoms and signs of stretch marks?
Striae are rarely painful or itchy. They do not produce troublesome symptoms. They begin as linear red streaks and eventually mature into linear white lines.
How are stretch marks diagnosed?
Since stretch marks are quite common, most people are familiar with their appearance. They are identifiable on visual inspection by patients and doctors.
What is the treatment for stretch marks?
There are a wide variety of treatments, but none of them seem to be particularly valuable in preventing or treating this condition. It is generally agreed that there is no good medical evidence that any creams or ointments will produce any sustained improvement in the appearance of stretch marks. The use of physical modalities such as lasers and ultrasound holds some promise, but time will tell if these treatments are effective.
Are there any home remedies for stretch marks?
No, there is no evidence that any home remedies can improve the appearance of stretch marks.
What is the prognosis of stretch marks?
As the striae mature, they become less apparent but they rarely disappear. They do not cause any health problems.
Can stretch marks be prevented?
Aside from maintaining a normal weight, there is little that can be done to prevent stretch marks from developing.

Heart Disease (Coronary Artery Disease)
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include:
- High blood pressure
- High cholesterol
- Family history
Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.
Lichen SclerosusLichen sclerosus is a skin disease that causes white spots to form on the skin, which later grow into large, thin, and crinkled patches of skin that tear easily. Symptoms include itching, pain, blisters, and bleeding. Patches on the upper body usually go away over time, but patches in the genital region may scar if left untreated, causing problems with urination or sex. Treatment may involve surgery or the use of a very strong cortisone cream.

SnoringSnoring, like all other sounds, is caused by vibrations that cause particles in the air to form sound waves. While we are asleep, turbulent air flow can cause the tissues of the nose and throat to vibrate and give rise to snoring. Any person can snore. Snoring is believed to occur in anywhere from 30% of women to over 45% of men. People who snore can have any body type. In general, as people get older and as they gain weight, snoring will worsen. Snoring can be caused by a number of things, including the sleep position, alcohol, medication, anatomical structure of the mouth and throat, stage of sleep, and mouth breathing.
Stretch Marks White Striae, AxillaStriae distensae, more commonly known as “stretch marks,” are atrophic linear bands of skin that appear after certain precipitating factors such as pregnancy, steroid use, and dramatic changes in weight or muscle mass. At presentation, they feature a purple or pink color (striae rubra) that fades to a paler white (striae alba) over time. They are most common in adult women. White striae, axilla. Prominent atrophy, textural changes, and depigmentation are observed.
