Menstruation
Menstruation is the monthly shedding of the endometrium or uterine lining. The menstrual cycle is controlled by rise and fall of hormone levels. In anticipation of an egg that is released during a month, the uterine lining is thickened with blood, tissue and fluid. This is in preparation for fertilization and possible pregnancy. When no fertilization occurs, the egg along with the uterine lining are shed throuh the cervix and into the vagina. This menstrual period occurs nearly once every 28 - 35 days. Each time it lasts for about 3 - 7 days. Anemia
Anemia stands for 'without blood' in Greek. When the number of red blood cells (RBC) falls below normal, Anemia is a resultant condition. Hemoglobin is an important constituent of RBC. Hemoglobin usually occurs in the range of 12 and 18 g/dL (grams per deciliter of blood). If the hemoglobin levels show a decrease, anemic conditions set in. Consequently, the various organs and tissues of the body do not receive adequate oxygen on account of the diminished oxygen carrying capacity of the blood. This impairs their normal functioning. Usually women have smaller stores of iron than men. Besides, they also lose blood during menstruation making them primary targets for anemia.
It is essential to be familiar with the typical symptoms of anemia. Often anemia is misdiagnosed and left untreated. An anemic person is likely to feel extremely tired and weak. This is accompanied with dizziness and breathlessness. A person suffering from anemia tends to appear pale and experience feelings of depression. In some cases, anemia can lead to heart ailments too.
Causes of Anemia
- Serious disease or infection such as hookworm infection, bleeding piles, esophagel varices and peptic ulcers
- Hemorrhagic - Excessive blood loss due to surgery, menstruation or injury
- Genetic defects lead to sickle cell anemia, Thalassemia anemia and aplastic anemia
- Hemoiytic - Excessive intravascular blood destruction where red blood cells are destroyed prematurely
Types of Anemia
Iron deficiency Anemia - Nearly 20% adult women tend to suffer from this form of anemia. Loss of blood due to menstruation is not compensated with an iron-rich diet Pregnancy and breast feeding can also deplete iron stores. Iron deficiency anemia is also noticed during growth spurts or internal bleeding.
Aplastic anemia - When the bone marrow does not produce sufficient quantities of blood cells, aplastic anemia is noticed. Childhood cancers such as leukemia are often responsible for this form of anemia. Other possible causes of aplastic anemia are radiation, cancer or antiseizure medications and chronic diseases such as thyroid or kidney malfunction. Treatment for aplastic anemia involves blood transfusions and bone marrow transplant. This is done to replace malfunctioning cells with healthy ones.
Vitamin deficiency anemia - Low levels of folic acid lead to faulty absorption of iron. Anemia caused due to folic acid deficiency is called megaloblastic anemia. Pregnancy doubles the body requirements of folic acid and it is imperative that pregnant women take folic acid supplements. Good dietary sources of folate are fresh fruits, green leafy vegetables, cruciferous vegetables, liver and kidney, dairy products and whole grain cereals. Vegetables should be eaten raw or lightly cooked.Folic acid anemia is also a common problem faced by alcoholics. Vitamin B-12 deficiency can lead to a condition of pernicious anemia. Diseases such as thyroid malfunction or diabetes mellitus can affect the body's ability to absorb vitamin B-12. This vitamin is vital in the production of hemoglobin.
Sickle cell anemia - Sickle cell anemia is a condition where the red blood cells change shape, from their original flexible round shape to a sickle or crescent shape. These irregular blood cells do not move smoothly. Instead they clog blood cells on account of their shape and consequently there is deprived oxgyen to various body parts. This blood disorder is genetic in origin and is found more predominantly in people of African, Mediterranean or Middle Eastern ancestry.
Thalassemia anemia - Thalassemia or Cooleys Disease is a heriditary disorder found predominantly in people of South East Asian, Greek and Italian racial groups. This form of anemia is seen in differing degrees as Thalaseemia encompasses a group of related disorders that affect the human body in similar ways. The most common occurences of Thalassemia are alpha and beta thalassemia. Thalassemia anemia is symptomized by jaundice, enlarged spleen, shortness of breath and facial bone deformities.
Diagnosing Anemia
A complete blood count test will test for hemoglobin levels and display an anemic condition. But often anemia is a symptom whose cause lies deeper. The cause and type of anemia will determine the treatment that is needed. A stool test will help in detecting occult blood. Hemoglobin electrophoresis is a blood test that helps identify abnormal hemoglobins. Diagnosing thalassemia or sickle cell anemia becomes possible with this test.
Treating Anemia
Deficiency can be treated with supplements of iron, Vitamin B-12 and Vitamin C. Partaking an iron-rich diet can be beneficial for those suffering from nutritional deficiency anemia. Seafood, nuts, whole grains and dried fruits such as raisins, prunes and apricots are rich in iron. Ensure adequate consumption of Vitamin C as it aids and stimulates iron absorption. Try and combine citrus foods with iron-rich foods - add tomatoes to a turkey sandwich or chopped strawberries with iron-fortified breakfast cereals.
Precocious Puberty
Precocious puberty is an uncommon condition that occurs when puberty begins before the age of eight in girls and before age nine in boys. The signs and symptoms of precocious puberty:
In Girls:
- Development of breasts
- Hair development underarm or in public parts
- Rapid height growth
- Onset of menstruation
- Acne
- Adult body odor
In Boys:
- Enlargement of testicles
- Hair growth in face (usually grows first on the upper lip), public parts /underarm
- Rapid height gain
- Deepening of voice
- Acne
- Adult body odor
In some children 'partial' precocious puberty could be seen. Girls may show breast development that later disappears or may persist without any other physical changes of puberty. Such children with partial precocious puberty should be evaluated by a medical professional to rule out any other health problems. By and large such instances do not require any treatment and usually will show the other expected signs of puberty at the right age.
Causes for Precocious Puberty
Abnormalities in ovary and testicles may contribute to precocious puberty. Problems in the ovaries, thyroid gland disorders can also cause the onset of puberty ahead of schedule. Sometimes precocious puberty is the result of a structural problem in the brain such as a tumor, brain injury due to head trauma, infection such as meningitis that triggers puberty to begin early. In a majority of girls there is no underlying medical problem but they simply start puberty too early for no known reason. Certain types of environmental contamination like environmental toxins could play a role in causing precocious puberty.
Central precocious puberty
- Tumor in the brain or spinal cord
- Infection such as encephalitis or meningitis
- A birth defect in the brain such as hydrocephalus or hamartoma (tumor)
- Radiation to brain or spinal cord
- Injury to brain or spinal cord
- Ischemia
- McCune Albright Syndrome - a genetic disease that affects the bones and skin color and causes hormonal problems
- A group of inherited disorders known as Congenital adrenal hyperplasia which involves abnormal hormone production by the adrenal glands.
- Hypothyroidism
