Menstruation is the time of month when the womb (uterus) sheds its lining and vaginal bleeding occurs. This is known as a menstrual period. Periods vary widely from woman to woman. Some periods are punctual, some are unpredictable. On average, a woman gets her period every 24 to 38 days. A period usually lasts about two to eight days. Irregular periods may require treatment. What Are Irregular Periods? You may have irregular periods if: The time between each period starts to change. You are losing more or less blood during a period than usual. The number of days that your period lasts varies significantly. There are different terms for different types of irregular periods: Irregular Menstrual Bleeding (IrregMB): Bleeding of more than 20 days in individual cycle lengths over a period of one year. Absent Menstrual Bleeding (amenorrhea): No bleeding in a 90-day period. Heavy Menstrual Bleeding (HMB): Excessive menstrual blood loss that interferes with the woman’s physical, emotional, social, and material quality of life and can occur alone or in combination with other symptoms. Heavy and Prolonged Menstrual Bleeding (HPMB): Less common than HMB. It is important to make a distinction from HMB given they may have different etiologies and respond to different therapies. Light Menstrual Bleeding: Based on patient complaint, rarely related to pathology.

Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. More fluid in your lungs means less oxygen can reach your bloodstream. This deprives your organs of the oxygen they need to function. ARDS typically occurs in people who are already critically ill or who have significant injuries. Severe shortness of breath — the main symptom of ARDS — usually develops within a few hours to a few days after the original disease or trauma. Many people who develop ARDS don't survive. The risk of death increases with age and severity of illness. Of the people who do survive ARDS, some recover completely while others experience lasting damage to their lungs.

Iron is a mineral that plays a vital role in health and well-being. Without it, many bodily functions would malfunction. “The primary role of iron is to carry oxygen in the blood to every cell in the body,” says Beth Thayer, RDN, MS, director of the Center for Health Promotion and Disease Prevention at Henry Ford Health System in Detroit. Iron is an important component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs and transports it throughout the body.

Men and women have anatomical differences when it comes to genitals, but orgasms are fundamentally very similar. The female orgasm lasts longer than the male, ranging about 20 seconds compared to 3 to 10 seconds, but men do experience more orgasms.

In lumbar stenosis, the spinal nerve roots in the lower back become compressed and this can produce symptoms of sciatica—tingling, weakness or numbness that radiates from the low back and into the buttocks and legs—especially with activity. Lumbar spinal stenosis often mimics symptoms of vascular insufficiency. Both conditions can cause claudication, which means leg pain with walking. If vascular studies identify normal blood flow, and there is confirmation of spinal stenosis on diagnostic testing, the symptoms are then called neurogenic claudication. In the classic description, people with spinal stenosis will describe an onset of leg pain, or weakness with walking, but with relief of symptoms with sitting. Many will also describe increased tolerance to walking when flexed forward, such as when walking while leaning forward on a shopping cart.

Cystic fibrosis (CF) is a multisystem disease affecting the digestive system, sweat glands, upper and lower respiratory tracts, and the reproductive tract, but progressive lung disease continues to be the major cause of morbidity and mortality [1]. CF is characterized by abnormal transport of chloride and sodium across the respiratory epithelium, resulting in thickened, viscous airway secretions [2]. Over a highly variable time course ranging from months to decades after birth, individuals eventually develop chronic infection of the respiratory tract with a characteristic array of bacterial flora [3], leading to progressive respiratory insufficiency and eventual respiratory failure. The rate of progression varies widely, depending in part on genotype (including gene modifiers) as well as environmental factors. Registry data from CF Centers in the United States, Canada, and Europe indicate a median survival of about 41 years [4]. Females with CF appear to have higher morbidity and mortality than males [5]. This "gender gap" is modest but consistent across many populations and is hypothesized to be due to the pro-inflammatory effects of estrogens.

Menstruation is a woman's monthly bleeding. When you menstruate, your body sheds the lining of the uterus (womb). Menstrual blood flows from the uterus through the small opening in the cervix and passes out of the body through the vagina. Most menstrual periods last from 3 to 5 days.

Sex reassignment surgery for male-to-female involves reshaping the male genitals into a form with the appearance of, and, as far as possible, the function of female genitalia. Prior to any surgeries, patients usually undergo hormone replacement therapy (HRT), and, depending on the age at which HRT begins, facial hair removal. There are associated surgeries patients may elect to, including facial feminization surgery, breast augmentation, and various other procedures.
