1 NUTRITION CHPT 11 Diet During Pregnancy & Lactation

2 How long is a pregnancy 38-40 weeks long

3 During pregnancy, who/what does mom provide nutrients to? Fetus - the growing baby Amniotic fluid – the fluid that surrounds the fetus in the womb Placenta – organ in the uterus that links blood supply from mom to fetus

4 Mom also provides nutrients to cause an increase in blood volume, breast and uterine and fat tissue She is not just eating for herself any more

5 Mental Retardation Is believed to be caused in part by malnutrition on the mothers part

6 Low birth weight Babies weighing less than 5.5 pounds

7 Weight gain with 1 baby during pregnancy 25-35 pounds over the 38-40 weeks Mom should increase her calories by 300 calories per day along with what she was used to eating

8 Trimesters A trimester consists of 3 months In pregnancy, there are 3 trimesters

9 Usually, women only gain 2-4 pounds in the 1 st trimester however… Weight gain should occur at a rate of 1 pound a week during the 2 nd and 3 rd trimester This wt gain is to aid in the growth of the increase in maternal tissue and in the growth of the fetus

10 Adolescent and weight gain A pregnant adolescent who is still growing needs more nutrients Adolescents already dont have healthy diets, probs occur d/t this Offer help from agencies like WIC, Birthright or other organizations Their weight gain depends on the size they are before pregnancy

11 Weight loss during pregnancy NO ONE SHOULD LOSE WEIGHT DURING PREGNANCY Malnutrition side effects could be worse than gaining weight

12 Folic Acid BEFORE a couple decides to become pregnant, they should visit the Dr. to discuss… Folic acid – its a water soluble vitamin, it aids in protein metabolism and formation of hemoglobin 400 mcg of Folic acid should be taken daily. Folic acid should be started 1 month before conception Folic acid deficiency causes spinal cord and brain defects, megablastic anemia where large immature RBCs dont carry O2 well

13 Megablastic anemia Its JUST LIKE ALL THE OTHER ANEMIAS: SOB Fatigue Weakness Pallor Bad RBCs which cant carry good O2

14 DIET DURING PREGNANCY Food pyramid should be followed NO HOLLOW CALORIES or EMPTY CALORIES

15 Vitamins & Supplements Folic acid – (member of the vit B complex) Vitamin A – fat soluble Vitamin D – fat soluble Vitamin E – fat soluble Vitamin K – fat soluble Iron (Fe)- to aid in the increase of blood volume during pregnancy

16 Vitamin C is an iron enhancer and increase absorption of iron Vitamin Bs they aid in metabolism and development of RBCs, water soluble Calcium to build bone and teeth, needed for blood clotting and muscle action

17 How important is iron? Due to increase blood volume, more iron is therefore needed. Doubled during pregnancy The fetus increases its hemoglobin level to twice its normal level while in the womb. After birth, the infants hemoglobin level is reduced back to normal as the extra hemoglobin breaks down. The resulting iron is stored in the liver and is available when needed Iron deficiency causes dizziness, weakness, S.O.B.

18 Drinking additional milk each day while pregnant provides: Protein Phosphorus Calcium And other nutrients

19 Problems During Pregnancy NAUSEA – the feeling of a need to vomit, usually lasts through to the end of the 1 st trimester A.K.A morning sickness although, nausea comes on at any time

20 Suggestions to help relieve morning sickness Eat dry crackers or dry toast before rising Eat small, frequent meals Avoid foods with an offensive odor Avoid liquids at mealtime

21 Hyperemesis Gravidarum Nausea so severe as to be life threatening Mother may need to be hospitalized for IV and food – parenteral nutrition Zofran given for nausea P.O. or I.V. Phenergan I.V or P.R. or P.O.

22 Parenteral Nutrition Nutrition provided through a vein called TPN (total parenteral nutrition) Parenteral – any med route other than the alimentary (mouth) canal such as I.V, SQ, IM Pt usually must be in the hospital for this type If home care nurse available and insurance, pt may get this at home

23 CONSTIPATION Progesterone is increased during the 3 rd trimester to get ready for baby to be born This causes relaxation of the cardiac sphincter and smooth muscle Cant push as strong, stool doesnt come out

24 Treatment of pregnancy related constipation Eating high fiber diet Daily exercise Drink plenty of fluids 8 glasses of water per day Respond immediately to the the urge to deficate

25 HEARTBURN As the fetus grows, it pushes on the moms stomach, this causes stomach acid to move into the lower esophagus causing heartburn

26 Relief of heartburn Eating small frequent meals vs. large meals Avoid spicy or greasy foods Avoid liquids with meals, you get too full Wait at least 1 hour before laying down after eating

27 Obesity Stay away from low nutrient dense foods like chips, sodas, candy Follow the food pyramid, drink lots of low- fat or fat-free milk Eat raw, crisp veggies, fruits and low-fat items

28 PIH Pregnancy induced hypertension (High blood pressure caused by pregnancy) A.K.A toxemia or preeclampsia Occurs in the 3 rd trimester S&S: HTN, proteinuria – albumin in the urine and edema

29 PIH The edema = wt gain This early stage can progress to the eclamptic state= seizures or convulsions and death

30 PIH, who gets it Adolescents Obese woman Women on inadequate protein sufficient diets First time pregnancies Multiple birth pregnancy

31 PICA Abnormal cravings for non-food substances such as: Starch like laundry detergent Clay or soil ice

32 Causes of PICA Unknown Believed to stop nausea More common in pregnant women Can be cultural

33 Anemia A condition caused by insufficient numbers of red blood cells, hemoglobin or blood volume Hemoglobin – the iron-containing pigment of the RBC that carries O2 Pt does not receive enough O2 from the blood and feels weak and tired

34 During pregnancy… The increased volume of blood creates the need for additional iron Baby takes what it needs from mom, mom is tired and deficient = anemia Can be treated with daily iron supplements

35 Folate Deficiency Results from a form of anemia There are too few RBCs and very large immature RBCs When new RBCs are being formed, the body needs more folic acid Supplement is given of folate = folic acid

36 Fetal Alcohol Syndrome Mental retardation or subnormal physical and mental developmental delays These infants are of low birth wt When mom drinks, it enters the fetal bloodstream but baby cannot metabolize the alcohol out

37 Physical Characteristics of FAS Small head (microcephaly) Short eye slits Flat midface Thin upper lip Ht and wt deficiency ADD or ADHD seizures

38 Caffeine Crosses the placenta and enters the babys bloodstream and causes fetus in womb or baby, to become irritable or hyperactive Pregnant rats who were given caffeine, showed that it caused birth defects in baby rats No data shows this in humans, mom should still limit caffeine to 2 cups/day

39 Tobacco and pregnancy Causes low birth wt Smoking reduces the O2 and nutrients carried by the blood and then baby cant get what it needs SIDS, spontaneous abortion (miscarriage occurring naturally), intellectual and behavioral problems can occur

40 Gestational Diabetes Diabetes that occurs during pregnancy and disappears after the delivery of baby Remember, Diabetes Mellitus is when one cannot use or store glucose normally d/t the inadequate production of insulin

41 What happens to baby if mom has gestational diabetes? Physical or mental defect in baby Stillborn Macrosomia – birth wt over 9 lbs Every woman is tested for diabetes btwn weeks 16-28 Insulin may be needed oral hypoglycemics are not recommended Mom will see a dietician

42 Lactation The period during which the mother is nursing the baby Breast milk is most nutritional for baby Breast milk contains the right amts of lactose, H2O, fatty acids and amino acids for brain development growth and digestion Human milk contain at least 100 ingredients not found in formula

43 How is moms milk made and released to baby Prolactin is responsible for milk production Oxytocin is responsible for milk ejection from the breast Baby sucking initiates the release of oxytocin, causing the let-down reflex to occur (this is a supply and demand mechanism)

44 Calorie requirements during lactation Increase of 500 calories per day while breastfeeding Must drink lots of water Increase in Vitamin C is needed Increase in milk to gain protein Natural wt loss occurs for mom by the burning of the stored fat for milk production during lactation

45 Medicine, caffeine, alcohol, tobacco Most chemicals enter the moms milk Moms diet can cause irritability in baby such as gas Check with Dr. as to what meds cross moms breast milk and into baby Mom may take drugs that cause addiction to her and baby

46 The End
