Heart Attack

Each year over a million people in the U.S. have a heart attack. About half of them die. Many people have permanent heart damage or die because they don't get help immediately. It's important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include
  • Chest discomfort - pressure, squeezing, or pain
  • Shortness of breath
  • Discomfort in the upper body - arms, shoulder, neck, back
  • Nausea, vomiting, dizziness, lightheadedness, sweating
These symptoms can sometimes be different in women.
What exactly is a heart attack? Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat – called an arrhythmia - that causes a severe decrease in the pumping function of the heart. A blockage that is not treated within a few hours causes the affected heart muscle to die.

Multiple Sclerosis

Multiple sclerosis (MS) is a nervous system disease that affects your brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects your nerve cells. This damage slows down or blocks messages between your brain and your body, leading to the symptoms of MS. They can include
  • Visual disturbances
  • Muscle weakness
  • Trouble with coordination and balance
  • Sensations such as numbness, prickling, or "pins and needles"
  • Thinking and memory problems
No one knows what causes MS. It may be an autoimmune disease, which happens when your body attacks itself. Multiple sclerosis affects women more than men. It often begins between the ages of 20 and 40. Usually, the disease is mild, but some people lose the ability to write, speak or walk. There is no cure for MS, but medicines may slow it down and help control symptoms. Physical and occupational therapy may also help.

Food safety

It is upsetting to think about, but the foods you eat to stay healthy can make you sick. Fortunately, there are many things you can do to protect yourself and your family from foodborne illness. There are things you can do in the grocery store, like avoiding cans that are bulging or jars that have cracks or loose lids. At home, you should
  • Be sure that your refrigerator and freezer are the right temperature for storing food
  • Refrigerate or freeze perishable foods right away
  • Throw away anything that looks or smells suspicious. If you think a food might be bad, don't taste it!
  • Wash your hands well before preparing food
  • Keep your work area, wash rags and utensils clean
  • Cook meats thoroughly

Infant and Newborn Nutrition

Food provides the energy and nutrients that babies need to be healthy. For a baby, breast milk is best. It has all the necessary vitamins and minerals. Infant formulas are available for babies whose mothers are not able or decide not to breastfeed.
Infants usually start eating solid foods between 4 and 6 months of age. Check with your health care provider for the best time for your baby to start. If you introduce one new food at a time, you will be able to identify any foods that cause allergies in your baby. Some foods to stay away from include eggs, honey, peanuts (including peanut butter) and other tree nuts.

Breast Feeding

Breast feeding offers many benefits to your baby. Breast milk contains the right balance of nutrients to help your infant grow into a strong and healthy toddler. Some of the nutrients in breast milk also help protect your infant against some common childhood illnesses and infections. It may also help your health. Certain types of cancer may occur less often in mothers who have breastfed their babies.
Women who don't have health problems should try to give their babies breast milk for at least the first six months of life. There are some cases when it's better not to breast feed. If you have HIV or active tuberculosis, you should not breast feed because you could give the infection to your baby. Certain medicines, illegal drugs, and alcohol can also pass through the breast milk and cause harm to your baby.

Caffeine

Caffeine is a bitter substance found in coffee, tea, soft drinks, chocolate, kola nuts, and certain medicines. It has many effects on the body's metabolism, including stimulating the central nervous system. This can make you more alert and give you a boost of energy.
For most people, the amount of caffeine in two to four cups of coffee a day is not harmful. However, too much caffeine can make you restless, anxious, and irritable. It may also keep you from sleeping well and cause headaches, abnormal heart rhythms, or other problems. If you stop using caffeine, you could get withdrawal symptoms.
Some people are more sensitive to the effects of caffeine than others. They should limit their use of caffeine. So should pregnant and nursing women. Certain drugs and supplements may interact with caffeine. If you have questions about whether caffeine is safe for you, talk with your health care provider.

Corneal Disorders

Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.
Problems with the cornea include
  • Refractive errors
  • Allergies
  • Infections
  • Injuries
  • Dystrophies—conditions in which parts of the cornea lose clarity due to a buildup of cloudy material
Treatments of corneal disorders include medicines, corneal transplantation and corneal laser surgery.

Female Infertility

Infertility is a term doctors use if a woman hasn’t been able to get pregnant after at least one year of trying. If a woman keeps having miscarriages, it is also called infertility. Female infertility can result from physical problems, hormone problems, and lifestyle or environmental factors.
Most cases of infertility in women result from problems with producing eggs. One problem is premature ovarian failure, in which the ovaries stop functioning before natural menopause. In another, polycystic ovary syndrome (PCOS), the ovaries may not release an egg regularly or may not release a healthy egg.
About a third of the time, infertility is because of a problem with the woman. One third of the time, it is a problem with the man. Sometimes no cause can be found.
If you suspect you are infertile, see your doctor. There are tests that may tell if you have fertility problems. When it is possible to find the cause, treatments may include medicines, surgery, or assisted reproductive technologies. Happily, two-thirds of couples treated for infertility are able to have babies.

Breast Cancer

Breast cancer affects one in eight women during their lives. Breast cancer kills more women in the United States than any cancer except lung cancer. No one knows why some women get breast cancer, but there are a number of risk factors. Risks that you cannot change include
  • Age - the chance of getting breast cancer rises as a woman gets older
  • Genes - there are two genes, BRCA1 and BRCA2, that greatly increase the risk. Women who have family members with breast or ovarian cancer may wish to be tested.
  • Personal factors - beginning periods before age 12 or going through menopause after age 55
Other risks include being overweight, using hormone replacement therapy, taking birth control pills, drinking alcohol, not having children or having your first child after age 35 or having dense breasts.
Symptoms of breast cancer may include a lump in the breast, a change in size or shape of the breast or discharge from a nipple. Breast self-exam and mammography can help find breast cancer early when it is most treatable. Treatment may consist of radiation, lumpectomy, mastectomy, chemotherapy and hormone therapy.
Men can have breast cancer, too, but the number of cases is small.

Pregnancy and Medicines

During pregnancy, any medicines you take, including over-the counter or prescription drugs, herbs, or supplements, can get into your baby's system. Some medicines may be safe, but many are not. The decision about whether or not to take a medicine depends on the risks and benefits. You and your health care provider should make this choice together. Labels on prescription and over-the-counter drugs have information that can help with the decision.
Always speak with your health care provider before you start or stop any medicine. Not using medicine that you need may be more harmful to you and your baby than using the medicine.

Twins, Triplets, Multiple Births

If you are pregnant with more than one baby, you are far from alone. Multiple births are way up in the United States. Why? More women are having babies after age 30 and more are taking fertility drugs. Both boost the chance of carrying more than one baby. A family history of twins also makes multiples more likely.
Years ago, most twins came as a surprise. Now, most women know about a multiple pregnancy early. They should see their health care providers more often than women who are expecting one baby because multiple pregnancies need to be monitored more closely. Multiple pregnancy babies have a much higher risk of being born prematurely. Some women have to go on bed rest to delay labor. Finally, they may deliver by C-section, especially if there are three babies or more.
Once babies are home, moms may feel overwhelmed and exhausted. Volunteer help and support groups for parents of multiples can ease the transition

Reproductive Health

Both the male and female reproductive systems play a role in pregnancy. Problems with these systems can affect fertility and the ability to have children. There are many such problems in men and women. Reproductive health problems can also be harmful to overall health and impair a person's ability to enjoy a sexual relationship.
Your reproductive health is influenced by many factors. These include your age, lifestyle, habits, genetics, use of medicines and exposure to chemicals in the environment. Many problems of the reproductive system can be corrected.

Cesarean Section

A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, about one in four women have their babies this way. Most C-sections are done when unexpected problems happen during delivery. These include
  • Health problems in the mother
  • The position of the baby
  • Not enough room for the baby to go through the vagina
  • Signs of distress in the baby
C-sections are also more common among women carrying more than one baby.
The surgery is relatively safe for mother and baby. Still, it is major surgery and carries risks. It also takes longer to recover from a C-section than from vaginal birth. After healing, the incision may leave a weak spot in the wall of the uterus. This could cause problems with an attempted vaginal birth later. However, more than half of women who have a C-section can give vaginal birth later

Infertility

Infertility means not being able to become pregnant after a year of trying. If a woman keeps having miscarriages, it is also called infertility. Lots of couples have infertility problems. About a third of the time, infertility can be traced to the woman. In another third of cases, it is because of the man. The rest of the time, it is because of both partners or no cause is found. Drugs or surgery are common treatments. Happily, two-thirds of couples treated for infertility go on to have babies.

Premature Babies

A premature baby, or preemie, is born before the 37th week of pregnancy. Premature birth occurs in between 8 percent to 10 percent of all pregnancies in the United States. Because they are born too early, preemies weigh much less than full-term babies. They may have health problems because their organs did not have enough time to develop. Preemies need special medical care in a neonatal intensive care unit, or NICU. They stay there until their organ systems can work on their own
