  • Depression during or after Pregnancy - Depression that occurs during pregnancy or within a year after delivery is called Perinatal Depression. The exact number of women with depression during this time is unknown. But researchers believe that depression is one of the most common complications during and after pregnancy. Often, the depression is not recognized or treated, because some normal pregnancy changes cause similar symptoms and are happening at the same time. Tiredness, problems sleeping, stronger emotional reactions, and changes in body weight may occur during pregnancy and after pregnancy. But these symptoms may also be signs of depression. There may be a number of reasons why a woman gets depressed. Hormone changes or a stressful life event, such as a death in the family, can cause chemical changes in the brain that lead to depression. Depression is also an illness that runs in some families. Other times, it’s not clear what causes depression.

  • Desire - A feeling of sexual attraction or arousal. The first stage of the sexual response cycle.

  • Diabetes - Diabetes means that your blood sugar is too high. Your blood always has some sugar in it because the body uses sugar for energy; it's the fuel that keeps you going. But too much sugar in the blood is not good for your health. Your body changes most of the food you eat into sugar. Your blood takes the sugar to the cells throughout your body. The sugar needs insulin to get into the body's cells. Insulin is a hormone made in the pancreas, an organ near the stomach. The pancreas releases insulin into the blood. Insulin helps the sugar from food get into body cells. If your body does not make enough insulin or the insulin does not work right, the sugar can't get into the cells, so it stays in the blood. This makes your blood sugar level high, causing you to have diabetes. If not controlled, diabetes can lead to blindness, heart disease, stroke, kidney failure, amputations (having a toe or foot removed, for example), and nerve damage. In women, diabetes can cause problems during pregnancy and make it more likely that your baby will be born with birth defects.

  • Douche – The word "douche" means to wash or soak in French. Douching is washing or cleaning out the vagina (also called the birth canal) with water or other mixtures of fluids. Usually douches are prepackaged mixes of water and vinegar, baking soda, or iodine. Women can buy these products at drug and grocery stores. The mixtures usually come in a bottle and can be squirted into the vagina through a tube or nozzle. Women douche because they mistakenly believe it gives many benefits. In reality, douching may do more harm than good.

  • Down Syndrome - Down syndrome is the most frequent genetic cause for mild to moderate mental retardation and related medical problems. It is caused by a chromosomal abnormality.
