Progesterone plays an important role during pregnancy. After delivery of the baby, the levels of this hormone begin to drop. Breastfeeding causes low levels of progesterone due to the effect of prolactin, which prevents ovulation. Thus, progesterone levels tend to be very low during this time.

The National Cholesterol Education Program, established in 1985, stresses the importance of getting your cholesterol checked at least every five years. Monitoring your cholesterol levels helps you to understand and control your risk for heart disease.

The amount of cholesterol in your blood is directly correlated with your risk of developing heart disease, the leading cause of death in the United States. Cholesterol tests involve drawing a blood sample from your arm to measure the level of cholesterol components in your blood.

Cholesterol is a type of fat that's made by the body and is also contained in many foods. While cholesterol is a normal and necessary part of your body's daily function, too much cholesterol can build up in your arteries, increasing your risk of cardiovascular disease.

Ferritin levels are indicated on a laboratory test that indirectly measures the amount of iron in a patient's body. Normal ferritin levels change as children age, but they typically fall between 6 and 55 ng/mL. Abnormal ferritin levels can indicate imbalances in iron metabolism that happen with problems like anemia.

Bananas, eaten in moderation, will more likely help than harm your cholesterol levels. They provide a good source of dietary fiber, which can help reduce your low-density lipoprotein – LDL or “bad” cholesterol. The potassium in bananas can also help lower your blood pressure, which may, in turn, lower your cholesterol.

Hormones are substances produced by the body that have chemical effects on other parts of the body. Women produce hormones, such as estradiol, follicle stimulating hormone (FSH), luteinizing hormone (LH) and progesterone. Certain hormones rise at various times of the menstrual cycle and during pregnancy.

Dehydroepiandrosterone, known as DHEA, has been termed the “mother” hormone for its vital role in creating androgens and estrogens. Normal levels of DHEA depend on age and sex, and women tend to have lower amounts than men.

Age is a major factor in the amount of cholesterol in your blood. Being older than 45 years old if you're a man and older than 55 if you're a woman is a "risk factor" for having a cholesterol problem, according to the U.S. government's National Cholesterol Education Program, or NCEP.

Human chorionic gonadotropin is a hormone that is most often associated with pregnancy in women. However, both males and nonpregnant females produce low levels of hCG throughout their lives as well.

Pregnancy is an intricate development of cells which multiply and eventually form a baby. Hormones play a complex role in this metamorphosis and assist physicians in determining the healthy progression of a pregnancy or potential problems.

Estrogen refers to a group of hormones present in the female body: estradiol, estriol and estrone. During the course of your life, the levels of these estrogen hormones fluctuate. They help to regulate your menstrual cycle and are also key in supporting and maintaining a healthy pregnancy.
