What is the linea alba?
The white line (Latin: linea alba) is a fibrous structure that runs down the midline of the abdomen in humans and other vertebrates. In humans linea alba runs from the xiphoid process to the pubic symphysis.
Linea Nigra is the Latin word that means “dark line”, and that is exactly what the Linea Nigrais, the dark vertical line that some women get on their stomach during pregnancy. Most women have the dark line on their stomach, and it usually runs from the belly button down to the pubic bone.
- It runs from your navel to the pubic bone. It darkens during pregnancy acquiring the name linea nigra (black line). The pregnancy line is never really black, however it is brownish and darker in color. It I is usually about ¼ to ½ inch wide and stretches vertically down your belly from the pubis to the umbilicus.
- If this is your first pregnancy, you may just feel bloated, kind of like after a big meal. But some women have a little baby-belly pooch by the end of the first trimester. After all, your uterus is now the size of a grapefruit. At your next exam, your doctor will be able to feel the top of it.
- If you are pregnant, by then the levels of hormone may be high enough to be picked up by the test. A blood test can also detect hCG. Blood tests are more sensitive than urine tests and may detect pregnancy from about six days to eight days after ovulation.
The linea nigra is the result of fluctuating hormones. One theory is that they cause your body to make more than the usual amount of melanin, a compound responsible for giving your skin pigment, and this extra pigmentation shows up as a dark line stretching from the belly button to the top of the pubic hair.
- An example of hyperpigmentation is melasma (also known as chloasma). This condition is characterized by tan or brown patches, most commonly on the face. Melasma can occur in pregnant women and is often called the "mask of pregnancy;" however, men can also develop this condition.
- Stretch marks are small, depressed streaks in the skin that appear most often on the abdomen in the later stages of pregnancy when the belly is rapidly expanding to accommodate a growing baby. Some women also get them on their buttocks, thighs, hips, and breasts.
- Pregnancy stretch marks, also known as striae gravidarum, is a specific form of scarring of the skin of the abdominal area due to rapid expansion of the uterus as well as sudden weight gain during pregnancy.
Pregnancy stretch marks, also known as striae gravidarum, is a specific form of scarring of the skin of the abdominal area due to rapid expansion of the uterus as well as sudden weight gain during pregnancy.
- After some time, these marks fade gradually to become less visible within 6 to 12 months, but the texture of these scars will remain constant, similar to initial stages. It's always better to prevent stretch marks from appearing in first place than worrying "do stretch marks go away" later.
- About 90 percent of women develop stretch marks (aka striae) during pregnancy. Stretch marks are actually tiny tears in the skin that usually appear on the tummy, breasts, hips and thighs. But there's some bad news: While stretch marks are likely to fade, they may never disappear altogether.
- If your mother had stretch marks, then you're more likely to have them too, since genetics plays a role. If you have a lighter complexion, you will tend to develop pinkish stretch marks. Darker-skinned women tend to get stretch marks that are lighter than their skin tone.
