KHAULA REHMAN MD FIRST TRIMESTER The first 12 weeks of pregnancy Fertilization Implantation in the uterus wall Placenta forms Formation of all body systems by the end of the first trimester, the fetus begins to move and takes a recognizable human shape , will be about 3 inches (76 mm) long and will weigh approximately 1 ounce (28 g). SECOND TRIMESTER Weeks 13 to 28 of the pregnancy . Once pregnancy moves into the second trimester, the risks of miscarriage and birth defects drop drastically Bodily changes are more apparent The movement of the fetus is usually felt in 19- 21 week Ultrasound can determine that baby is male or female THIRD TRIMESTER The fetus will be growing the most rapidly during this stage, gaining up to 28 g per day. This period of pregnancy can be uncomfortable, causing symptoms like weak bladder control and backache. There is head engagement in the third trimester, that is, the fetal head descends into the pelvic cavity Embryo at 4 weeks after fertilization Fetus at 8 weeks after fertilization Fetus at 18 weeks after fertilization Fetus at 38 weeks after fertilization NUTRITION AND PREGNANCY A balanced, nutritious diet ,including carbohydrates, fat, and protiens. eating a variety of fruits and vegetables. Start prenatal vitamins. Adequate peri-conceptional folic acid intake has been proven to limit fetal neural tube defects, preventing spina bifida a very serious birth defect. The neural tube develops during the first 28 days of pregnancy. NUTRITION AND PREGNANCY Folic acid is abundant in green leafy vegetables as spinach , salads, beets, broccoli, asparagus, citrus fruits and melons, chickpeas and eggs. In the United States and Canada, most wheat products flour, noodles and cereals are fortified with folic acid. Foods That should avoided during pregnancy Raw Meat: Uncooked seafood and rare or undercooked beef or poultry should be avoided because of the risk of contamination with coliform bacteria, toxoplasmosis and salmonella. Deli Meat: Deli meats have been known to be contaminated with listeria, which can cause miscarriage. Listeria has the ability to cross the placenta and may infect the baby leading to infection or blood poisoning, which may be life-threatening. If you are pregnant and you are considering eating deli meats, make certain that you reheat the meat until it is steaming . Foods That should avoided during pregnancy Raw Eggs: Raw eggs or any foods that contain raw eggs should be avoided because of the potential exposure to salmonella. Some homemade Caesar dressings, mayonnaise, homemade ice cream or custards can have raw eggs. If the recipe is cooked at some point, this will reduce the exposure to salmonella. Commercially manufactured ice cream, dressings, and eggnog are made with pasteurized eggs and do not increase the risk of salmonella. Foods That should avoided during pregnancy Un pasteurized Milk: Un pasteurized milk may contain a bacteria called listeria, which can be life-threatening for the baby. Make sure that any milk you drink is pasteurized. Soft Cheese: You would need to avoid soft cheeses such as: Brie, Camembert, Roquefort, Feta, Gorgonzola and Mexican style cheeses that include queso blanco and queso fresco, unless they clearly state that they are made from pasteurized milk. Foods That should avoided during pregnancy Unwashed Vegetables: Vegetables are safe to eat. However, it is essential to make sure they are washed to avoid potential exposure to toxoplasmosis. Foods That should avoided during pregnancy Caffeine: Although most studies show that caffeine intake in moderation is OK, there are others that show that caffeine intake may be related to miscarriages, premature birth, low birth weight, and withdrawal symptoms in infants. The safest thing is to refrain from consuming caffeine. If you cannot avoid it than it should be less than 200 mg per day during pregnancy. Alcohol: There is NO amount of alcohol that is known to be safe during pregnancy. It can cause fetal alcohol syndrome Foods That should avoided during pregnancy Fish with Mercury: Fish that contain high levels of mercury should be avoided. Mercury consumed during pregnancy has been linked to developmental delays and brain damage. A sample of these types of fish include: shark, swordfish, king mackerel, and tilefish. Canned, chunk light tuna generally has a lower amount of mercury than other tuna, but still should only be eaten in moderation. Certain types of fish used in Sushi should also be avoided due to high levels of mercury. Fish Exposed to Industrial Pollutants: Avoid fish from contaminated lakes and rivers that may be exposed to high levels of polychlorinated biphenyls. This is primarily for those who fish in local lakes and streams. These fish include: bluefish, striped bass, salmon, pike, trout, and walleye. Contact the local health department or Environmental Protection Agency to determine which fish are safe to eat in your area. Remember, this is regarding fish caught in local waters and not fish from your local grocery store. WEIGHT GAIN AND PREGNANCY Caloric intake must be increased to ensure proper development of the fetus. . The Institute of Medicine recommends an overall pregnancy weight gain for women starting pregnancy at a normal of 25– 35 pounds Overweight women are advised to gain between 15–25 lbs, Obese woman to gain between 11–20 lbs. Doctors and dietitians may make different, or more individualized, recommendations for specific patients, based on factors including low maternal age, nutritional status, fetal development, and morbid obesity. WEIGHT GAIN AND PREGNANCY During pregnancy, insufficient or excessive weight gain can compromise the health of the mother and fetus. All women are encouraged to choose a healthy diet regardless of pre-pregnancy weight. Exercise during pregnancy, such as walking and swimming, is recommended for healthy pregnancies. Exercise has notable health benefits for both mother and baby, including preventing excessive weight gain. United States FDA Pharmaceutical Pregnancy Categories Pregnancy Category A Adequate and well-controlled human studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters). Pregnancy Category B Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women OR Animal studies have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester. Pregnancy Category C Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. Pregnancy Category D There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. Pregnancy Category X Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.

SIGNS & SYMPTOMS WATCHED DURING PREGNANCY Check your BP regularly If headaches, swelling of your hands, feet and legs call your doctor pay attention to the baby’s movements ASTHMA AND PREGNANCY Asthma affects over 20 million Americans and is one of the most common potentially serious medical conditions to complicate pregnancy. Poorly controlled asthma can lead to serious medical problems for pregnant women and their fetuses. Maternal asthma is associated with increased risk of infant death, preeclampsia (a serious condition marked by high blood pressure, which can cause seizures in the mother or fetus), premature birth, and low-birth weight. Simply put, when a pregnant patient has trouble breathing, her fetus also has trouble getting the oxygen it needs NAEPP guidelines for treating asthma during pregnancy We cannot predict whose asthma will worsen during pregnancy. Generally asthma in 1/3 of the women will stay the same, in 1/3 it will improve and in 1/3 it will get worse. so the new guidelines recommend that pregnant patients with persistent asthma have their asthma checked at least monthly by a healthcare provider. NAEPP guidelines for treating asthma during pregnancy Albuterol, a short-acting inhaled beta2-agonist, should be used as a quick-relief medication to treat asthma symptoms. Pregnant women with asthma should have this medication available at all times. Women who have symptoms at least two days a week or two nights a month have persistent asthma and need daily medication for long-term care of their asthma and to prevent exacerbations. Inhaled corticosteroids are the preferred medication to control the underlying inflammation in pregnant women with persistent asthma. The guidelines note that there are more data on the safety of budesonide use during pregnancy than on other inhaled corticosteroids NAEPP guidelines for treating asthma during pregnancy For patients whose persistent asthma is not well controlled on low doses of inhaled corticosteroids alone, the guidelines recommend either increasing the dose of inhaled corticosteroid or adding another medication — a long-acting beta agonist. Oral corticosteroids may be required for the treatment of severe asthma. The guidelines note that there are conflicting data regarding the safety of oral corticosteroids during pregnancy; however, severe, uncontrolled asthma poses a definite risk to the mother and fetus; and use of oral corticosteroids may be warranted. ASTHMA AND PREGNANCY prospective studies found no relation between taking inhaled corticosteroids and congenital abnormalities or other adverse pregnancy outcomes leukotriene receptor antagonists, cromolyn, theophylline , and antihistamines should be avoided Important aspects of asthma management during pregnancy Identifying and limiting exposure to asthma triggers Women with other conditions that can worsen asthma, such as allergic rhinitis, sinusitis, and gastro-esophageal reflux, should have these conditions treated as well by their Physician. Tobacco smoke or allergens like dust mites should be avoided DIABETES AND PREGNANCY Criteria for very high risk are: Severe obesity Prior history of GDM or delivery of large baby Presence of glycosuria Diagnosis of PCOS Strong family history of type 2 diabetes DIABETES AND PREGNANCY High blood glucose levels before and during pregnancy can worsen your long-term diabetes complications, such as vision problems, heart disease, and kidney disease Increase the chance of problems for your baby, such as being born too early, weighing too much or too little, and having low blood glucose or other health problems at birth Increase the risk of your baby having birth defects increase the risk of losing your baby through miscarriage or stillbirth However, research has shown that when women with diabetes keep blood glucose levels under control before and during pregnancy, the risk of birth defects is about the same as in babies born to women who don't have diabetes. DIABETES AND PREGNANCY Plan your pregnancy. See your doctor. Get your diabetes under good control. Monitor your blood sugar often. Pregnancy affects your blood sugar control. You will probably need to check your blood sugar more often than when you are not pregnant. Talk with your doctor about how often to check your blood sugar. Take your medications on time. If medications are ordered by a doctor, take them as directed. Control and treat low blood sugar quickly. Having tight blood sugar control can lead to a chance of low blood sugar at times. Keep a ready source of sugar, such as glucose tablets or gel or hard candy, on hand at all times. Talk with your doctor about how to treat low blood sugar. Follow up with the doctor regularly. You will need to see your doctor more often than a pregnant woman without diabetes. Together, you can work with your doctor to prevent or catch problems early. If you had gestational diabetes, talk with your doctor about getting your blood sugar checked after delivery and every 1 - 3 years. About half of all women who had gestational diabetes develop type 2 diabetes later. PRE-ECLAMPSIA Preeclampsia is a condition that typically starts after the 20th week of pregnancy and is related to increased blood pressure and protein in the mother's urine . Preeclampsia affects the placenta, and it can affect the mother's kidney, liver, and brain. When preeclampsia causes seizures, the condition is known as eclampsia -the second leading cause of maternal death in the U.S. Pre-eclampsia is also a leading cause of fetal complications, which include low birth weight, premature birth, and stillbirth Who Is More Likely to Develop Preeclampsia? Women with chronic hypertension, Diabetes and kidney disease. Women who developed high blood pressure or preeclampsia during a previous pregnancy, especially if these conditions occurred early in the pregnancy. Women who are obese prior to pregnancy. Pregnant women under the age of 20 or over the age of 40. Women who are pregnant with more than one baby. SYMPTOMS OF PRE-ECLAMPSIA Increased BP Swelling Protien in the urine Headache Abdominal pain TREATMENT OF PREECLAMPSIA The only cure is Delivery of the baby Medications to lower blood pressure. Corticosteroids. can temporarily improve liver and platelet functioning to help prolong your pregnancy. Corticosteroids can also help your baby's lungs become more mature in as little as 48 hours — an important step in helping a premature baby prepare for life outside the womb. Anticonvulsive medications. If your preeclampsia is severe, your doctor may prescribe an anticonvulsive medication, such as magnesium sulfate, to prevent a first seizure.
