folacin

Folic acid is a B vitamin. It helps the body make healthy new cells. Everyone needs folic acid. For women who may get pregnant, it is really important. Getting enough folic acid before and during pregnancy can prevent major birth defects of her baby's brain or spine.

Foods with folic acid in them include:

• Leafy green vegetables
• Fruits
• Dried beans, peas, and nuts
• Enriched breads, cereals and other grain products

If you don't get enough folic acid from the foods you eat, you can also take it as a dietary supplement.

Nutrition is about eating a healthy and balanced diet so your body gets the nutrients that it needs. Nutrients are substances in foods that our bodies need so they can function and grow. They include carbohydrates, fats, proteins, vitamins, minerals, and water.

When you're pregnant, nutrition is more important than ever. You need more of many important nutrients than you did before pregnancy. Making healthy food choices every day will help you give your baby what they need to develop. It will also help make sure that you and your baby gain a healthy amount of weight.

You need more folic acid, iron, calcium, and vitamin D than you did before pregnancy:

• Folic acid is a B vitamin that may help prevent neural tube defects.
  • Before pregnancy, you need 400 mcg (micrograms) per day.
  • During pregnancy and when breastfeeding, you need 600 mcg per day from foods and/or vitamins. It is hard to get this amount from foods alone, so you will most likely need to take a supplement that contains folic acid.
• Iron is important for your baby's growth and brain development. During pregnancy, the amount of blood in your body increases, so you need more iron for yourself and your growing baby. You should get 27 mg (milligrams) of iron a day.
• Calcium during pregnancy can reduce your risk of preeclampsia. It's a serious medical condition that causes a sudden increase in your blood pressure. Calcium also builds up your baby's bones and teeth.
• Pregnant adults should get 1,000 mg (milligrams) of calcium a day
• Pregnant teenagers (ages 14-18) need 1,300 mg of calcium a day
• Vitamin D helps the calcium to build up the baby's bones and teeth. All women, pregnant or not, should be getting 600 IU (international units) of vitamin D per day.

Keep in mind that taking too much of a supplement can be harmful. For example, very high levels of vitamin A can cause birth defects. Only take vitamins and mineral supplements that your health care provider recommends.

You also need more protein when you are pregnant. Healthy sources of protein include beans, peas, eggs, lean meats, seafood, and unsalted nuts and seeds.

Getting enough fluids is another special nutritional concern during pregnancy. When you are pregnant, your body needs even more water to stay hydrated and support the life inside you. So it's important to drink enough fluids every day.

How much weight you should gain depends on your health and how much you weighed before pregnancy:

• If you were at a normal weight before pregnancy, you should gain about 25 to 35 pounds
• If you were underweight before pregnancy, you should gain more
• If you were overweight or had obesity before you became pregnant, you should gain less

Check with your provider to find out how much weight gain during pregnancy is healthy for you. You should gain the weight gradually during your pregnancy, with most of the weight gained in the last trimester.

How many calories you need depends on your weight gain goals. Your provider can tell you what your goal should be, based on things like your weight before pregnancy, your age, and how fast you gain weight. The general recommendations are:

• In the first trimester of pregnancy, you probably do not need extra calories
• In the second trimester, you usually need about 340 extra calories
• In the last trimester, you may need around 450 extra calories per day
• During the final weeks of pregnancy, you may not need extra calories

Keep in mind that not all calories are equal. You should eat healthy foods that are packed with nutrients - not "empty calories" such as those found in soft drinks, candies, and desserts.

During pregnancy, you should avoid:

• Alcohol. There is no known amount of alcohol that is safe for a woman to drink during pregnancy.
• Fish that may have high levels of mercury. Limit white (albacore) tuna to 6 ounces per week. Do not eat tilefish, shark, swordfish, marlin, orange roughy, or king mackerel.
• Foods that are more likely to contain germs that could cause foodborne illness, including
  • Refrigerated smoked seafood like whitefish, salmon, and mackerel
  • Undercooked meat, poultry, eggs, and seafood
  • Refrigerated meat spreads
  • Store-made salads, such as chicken, egg, or tuna salad
  • Unpasteurized or raw milk
  • Unpasteurized juices or cider
  • Unpasteurized soft cheeses, such as unpasteurized feta, Brie, queso blanco, queso fresco, and blue cheeses
  • Raw sprouts of any kind (including alfalfa, clover, radish, and mung bean)
  • Raw cookie dough
  • Unwashed fruits and vegetables
• Too much caffeine. Drinking high amounts of caffeine may be harmful for your baby. For most people, it's best to limit caffeine to less than 200 mg per day during pregnancy. But first check with your provider about whether you should have caffeine at all.

A birth defect is a problem that happens while a baby is developing in the mother's body. Most birth defects happen during the first 3 months of pregnancy. One out of every 33 babies in the United States is born with a birth defect.

A birth defect may affect how the body looks, works, or both. Some birth defects like cleft lip or neural tube defects are structural problems that can be easy to see. Others, like heart disease, are found using special tests. Birth defects can range from mild to severe. How a birth defect affects a child's life depends mostly on which organ or body part is involved and how severe the defect is.

For some birth defects, researchers know the cause. But for many birth defects, the exact cause is unknown. Researchers think that most birth defects are caused by a complex mix of factors, which can include:

• Genetics. One or more genes might have a change or mutation that prevents them from working properly. For example, this happens in Fragile X syndrome. With some defects, a gene or part of the gene might be missing.
• Chromosomal problems. In some cases, a chromosome or part of a chromosome might be missing. This is what happens in Turner syndrome. In other cases, such as with Down syndrome, the child has an extra chromosome.
• Exposures to medicines, chemicals, or other toxic substances. For example, alcohol misuse can cause fetal alcohol spectrum disorders.
• Infections during pregnancy. For example, infection with Zika virus during pregnancy can cause a serious defect in the brain.
• Lack of certain nutrients. Not getting enough folic acid before and during pregnancy is a key factor in causing neural tube defects.

Certain factors may increase the chances of having a baby with a birth defect, such as:

• Smoking, drinking alcohol, or taking certain "street" drugs during pregnancy
• Having certain medical conditions, such as obesity or uncontrolled diabetes, before and during pregnancy
• Taking certain medicines
• Having someone in your family with a birth defect. To learn more about your risk of having a baby with a birth defect, you can talk with a genetic counselor,
• Being an older mother, typically over the age of 34 years

Health care providers can diagnose some birth defects during pregnancy, using prenatal testing. That's why it important to get regular prenatal care.

Other birth defects may not be found until after the baby is born. Providers may find them through newborn screening. Some defects, such as club foot, are obvious right away. Other times, the health care provider may not discover a defect until later in life, when the child has symptoms.

Children with birth defects often need special care and treatments. Because the symptoms and problems caused by birth defects vary, the treatments also vary. Possible treatments may include surgery, medicines, assistive devices, physical therapy, and speech therapy.

Often, children with birth defects need a variety of services and may need to see several specialists. The primary health care provider can coordinate the special care that the child needs.

Not all birth defects can be prevented. But there are things you can do before and during pregnancy to increase your chance of having a healthy baby:

• Start prenatal care as soon as you think you might be pregnant, and see your health care provider regularly during pregnancy
• Get 400 micrograms (mcg) of folic acid every day. If possible, you should start taking it at least one month before you get pregnant.
• Don't drink alcohol, smoke, or use "street" drugs
• Talk to your health care provider about any medicines you are taking or thinking about taking. This includes prescription and over-the-counter medicines, as well as dietary or herbal supplements.
• Learn how to prevent infections during pregnancy
• If you have any medical conditions, try to get them under control before you get pregnant

Neural tube defects are birth defects of the brain, spine, or spinal cord. They happen in the first month of pregnancy, often before a woman even knows that she is pregnant. The two most common neural tube defects are spina bifida and anencephaly. In spina bifida, the fetal spinal column doesn't close completely. There is usually nerve damage that causes at least some paralysis of the legs. In anencephaly, most of the brain and skull do not develop. Babies with anencephaly are usually either stillborn or die shortly after birth. Another type of defect, Chiari malformation, causes the brain tissue to extend into the spinal canal.

The exact causes of neural tube defects aren't known. You're at greater risk of having an infant with a neural tube defect if you:

• Have obesity
• Have poorly controlled diabetes
• Take certain antiseizure medicines

Getting enough folic acid, a type of B vitamin, before and during pregnancy prevents most neural tube defects.

Neural tube defects are usually diagnosed before the infant is born, through lab or imaging tests. There is no cure for neural tube defects. The nerve damage and loss of function that are present at birth are usually permanent. However, a variety of treatments can sometimes prevent further damage and help with complications.

If you are trying to have a baby or are just thinking about it, it is not too early to prepare for a safe pregnancy and a healthy baby. You should see your health care provider for preconception care.

Preconception care is care you receive before you get pregnant. Your health care provider can help you figure out which steps you need to take now, such as:

• Finding and taking care of any problems that might affect you and your baby later, like diabetes or high blood pressure
• Increasing the amount of folic acid you get to prevent neural tube defects
• Getting up to date on vaccines
• Avoiding smoking, drinking alcohol, or taking drugs
• Trying to reach a healthy weight

By taking action on health issues before pregnancy, you can prevent many future problems for yourself and your baby. Once you're pregnant, you'll get prenatal care until your baby is born.

Not all medicines are safe to take when you are pregnant. Some medicines can harm your baby. That includes over-the-counter or prescription drugs, herbs, and supplements.

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. For example, many pregnant women take prescription medicines for health problems like diabetes, asthma, seizures, and heartburn. 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.

Pregnant women should not take regular vitamins. They may have too much or too little of the vitamins that you need. There are special vitamins for pregnant women. It is important to take 0.4 mg of folic acid every day before you become pregnant through the first part of your pregnancy. Folic acid helps to prevent birth defects of the baby's brain or spine.

Spina bifida is a neural tube defect - a type of birth defect of the brain, spine, or spinal cord. It happens if the spinal column of the fetus doesn't close completely during the first month of pregnancy. This can damage the nerves and spinal cord. Screening tests during pregnancy can check for spina bifida. Sometimes it is discovered only after the baby is born.

The symptoms of spina bifida vary from person to person. Most people with spina bifida are of normal intelligence. Some people need assistive devices such as braces, crutches, or wheelchairs. They may have learning difficulties, urinary and bowel problems, or hydrocephalus, a buildup of fluid in the brain.

The exact cause of spina bifida is unknown. It seems to run in families. Taking folic acid can reduce the risk of having a baby with spina bifida. It's in most multivitamins. Women who could become pregnant should take it daily.

If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.

Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

Conditions that may lead to anemia include:

• Heavy periods
• Pregnancy
• Ulcers
• Colon polyps or colon cancer
• Inherited disorders
• A diet that does not have enough iron, folic acid or vitamin B12
• Blood disorders such as sickle cell anemia and thalassemia, or cancer
• Aplastic anemia, a condition that can be inherited or acquired
• G6PD deficiency, a metabolic disorder

Anemia can make you feel tired, cold, dizzy, and irritable. You may be short of breath or have a headache.

Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have.

The B vitamins are:

• B1 (thiamine)
• B2 (riboflavin)
• B3 (niacin)
• B5 (pantothenic acid)
• B6
• B7 (biotin)
• B12
• Folic acid

These vitamins help the process your body uses to get or make energy from the food you eat. They also help form red blood cells. You can get B vitamins from proteins such as fish, poultry, meat, eggs, and dairy products. Leafy green vegetables, beans, and peas also have B vitamins. Many cereals and some breads have added B vitamins.

Not getting enough of certain B vitamins can cause diseases. A lack of B12 or B6 can cause anemia.

Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. When you are pregnant, high blood sugar levels are not good for your baby.

About seven out of every 100 pregnant women in the United States get gestational diabetes. Gestational diabetes is diabetes that happens for the first time when a woman is pregnant. Most of the time, it goes away after you have your baby. But it does increase your risk for developing type 2 diabetes later on. Your child is also at risk for obesity and type 2 diabetes.

Most women get a test to check for diabetes during their second trimester of pregnancy. Women at higher risk may get a test earlier.

If you already have diabetes, the best time to control your blood sugar is before you get pregnant. High blood sugar levels can be harmful to your baby during the first weeks of pregnancy - even before you know you are pregnant. To keep you and your baby healthy, it is important to keep your blood sugar as close to normal as possible before and during pregnancy.

Either type of diabetes during pregnancy increases the chances of problems for you and your baby. To help lower the chances talk to your health care team about:

• A meal plan for your pregnancy
• A safe exercise plan
• How often to test your blood sugar
• Taking your medicine as prescribed. Your medicine plan may need to change during pregnancy.
