Dr Rania Hussein
2. Nausea and vomiting:
morning sickness
• Occur early in pregnancy: 6
weeks after the start of last
menstrual period and last for 6
weeks
• The cause may be hormonal
changes during early pregnancy
Dr Rania Hussein
3. Treatment
1. Keep stomach filled but not overfilled
2. Eat small frequent meals
3. Separate consumption of fluids and
solid foods.
4. Consume easily digested foods
5. Avoid strong-flavored foods
6. When nauseated , do not drink fluids,
but eat toast or crackers.
Dr Rania Hussein
4. Heart burn
It is caused by:
• Relaxation of muscles →↓ gastric
emptying → esophageal
regurgitation.
• In late pregnancy, the pregnant
uterus compresses the diaphragm .
Treatment:
5. Eating small frequent meals
6. Avoiding lying down soon after
meals
7. Antacids can be used
Dr Rania Hussein
5. Constipation
It is caused by:
2. ↓ physical activity
3. ↓ intestinal motility
4. ↓water intake
5. ↓ fiber intake in diet
6. The enlarging uterus exerts
pressure on the bowel
Dr Rania Hussein
6. Treatment of constipation
1. Adequate fluid intake
2. Increasing dietary fiber
3. Use of bulking agents as bran→ flatulence
and bloating
Dr Rania Hussein
7. Craving and aversion
• Craving and aversion are powerful urges to
consume or not consume particular foods or
beverages, including foods that were neither
craved nor considered avulsive before.
• Food craving may range from pickles to ice
cream.
• Food aversion are usually to coffee and meat.
Dr Rania Hussein
8. • Pica is the ingestion of non food substances as
clay.
• May be due to the body’s search for a source
of nutrients it is lacking.
Dr Rania Hussein
10. Benefits
• A positive self image
• Maintenance of fitness
• Shorter labor, and fewer surgical
interventions
Dr Rania Hussein
11. Recommendations
1. Avoidance of activities with excessive twists
and turns, or those that may cause
abdominal trauma.
2. A carbohydrate snack before exercise to
sustain blood glucose.
Dr Rania Hussein
13. Maternal and family conditions
• Age: adolescent – older gravida
• Low SE socioeconomic status
• History of poor pregnancy outcome
• Short inter pregnancy interval
• High parity
Dr Rania Hussein
14. Maternal health problems and
Prenatal complicated pregnancy
• Obesity, underweight, or poor gestational weight
gain
• Hyperemesis gravidarum
• Multiple fetuses
• Anemia
• Hypertensive disorders of pregnancy
• DM
• Viral infections (HIV, Rubella)
Dr Rania Hussein
18. 1. ↓ nutrient stores
and ↑ nutritional needs :
• Adolescents are still in growth phase →
Competition for nutrients between
mother and fetus →↓ placental blood
flow → premature or low birth weight
babies.
2. Smaller pelvis of the young adolescent
mother → cephalopelvic disproportion
→ difficulties in delivery
Dr Rania Hussein
19. 2. Is likely to be poor
2. → ↓ intake of nutrients → ↓ prepregnancy
weight and ↓ gestational weight
3. Late entry to prenatal care
Dr Rania Hussein
20. Consequences of pregnancy in
adolescence
1. Preterm delivery
2. Low birth weight infant
3. Difficult labor and delivery
4. Pregnancy- induced hypertension
Dr Rania Hussein
21. Recommended energy and nutrient
intake for the pregnant adolescent
Energy levels greater than the additional
300Kcal/day are recommended.
RDA for protein is increased by 15 g/day
Iron, Folate, and calcium supplementation
should be recommended routinely
Dr Rania Hussein
23. Taking care of the pregnant
adolescent
1. Family should be supportive
and more sympathetic
2. Ensure prenatal and postnatal
care
Dr Rania Hussein
24. Older gravida (35 years and older )
Risks:
2. Multiple fetuses
3. Medical conditions : DM, cardiovascular diseases,
obesity, tumors
4. Down syndrome
5. Preterm infants
6. Low birth weight infants
7. Maternal and perinatal mortality
Dr Rania Hussein
25. Socioeconomic status
They include:
2. Social status
3. Income
4. Education
5. Employment
6. Marital status
7. Availability of health care systems
Dr Rania Hussein
26. Consequences of low
socioeconomic status
↓ maternal weight gain →
• Preterm infants
• Low birth weight infants
Dr Rania Hussein
28. Underweight mothers are at
higher risk of having
1. Low-birth-weight infants
2. Preterm delivery
Dr Rania Hussein
29. Obese women are at a greater
risk of having
• Hypertension.
• Diabetes.
• Complications during labor: Fetal
macrosomia and shoulder dystocia
• Thromboembolism
• Obesity may double the risk of NTD
Dr Rania Hussein
30. Multiple births
Consequences:
2. Preterm infants
3. Low birth weight infants
Energy and nutrient requirements are increased
Weight gain should exceed that of single
pregnancies (about 22 Kg weight gain in
twin pregnancy)
Dr Rania Hussein
31. Hyperemesis gravidarum
• It is a nutritionally debilitating condition
characterized by intractable vomiting that
develops during the first 22 weeks of
gestation.
• Cause is unknown , but may be due to
hormonal changes during pregnancy.
Dr Rania Hussein
32. Complications include;
2. Weight loss, dehydration, electrolyte
imbalance
3. Fetal growth restriction
4. Utilization of body fats and proteins,
ketonemia→ this impairs neurologic
development of the fetus
Dr Rania Hussein
33. Treatment
1. Hospitalization
2. Intravenous fluids to correct dehydration and
electrolyte imbalance
3. Correction of ketonemia
4. Oral intake is slowly introduced (small
frequent meals low in fat, high in
carbohydrates, with liquids consumed at
different times)
Dr Rania Hussein
34. If the woman fails to respond to oral feeding,
food is introduced either through a commercial
formula via tube into the stomach (enteral
feeding), or nutrient needs are given by
intravenous infusion (parenteral nutrition)
Dr Rania Hussein
36. • It is a chronic disorder in which blood levels
of glucose are elevated.
• The cause is either insulin deficiency or
resistance,
• Net result is hyperglycemia.
Dr Rania Hussein
37. Types of DM are:
• Type 1 Insulin dependant diabetes
• Type 2 Non insulin dependant diabetes
• Gestational diabetes
Dr Rania Hussein
38. In all types of Diabetes in Pregnancy
↑maternal blood glucose → blood glucose passes
to the fetus → fetal pancreatic insulin
secretion → ↑ protein and fat synthesis in
fetus→ macrosomia
Dr Rania Hussein
39. Consequences of Diabetes
• Preeclampsia
• Frank diabetes later in life.
• Fetal macrosomia and birth injuries
• Operative delivery
• Neonatal hypoglycemia
• Congenital anomalies
Dr Rania Hussein
40. In pregestational diabetes,
• Insulin requirements ↓in the first half of
pregnancy, as the fetus uses some of mother’s
glucose.
• Insulin requirements↑ In the second half of
pregnancy, due to hormonal changes.
Dr Rania Hussein
41. Gestational Diabetes: GD
• Intolerance to carbohydrates, first
recognized in pregnancy.
• Late in the 2nd trimester.
• Carbohydrate tolerance is normal
before pregnancy and after
delivery.
Dr Rania Hussein
42. Nutrition goals in the management of
gestational diabetes
1. Provide necessary nutrients to the fetus and
mother
2. Maintain normal blood glucose
(euglycemia), and prevent ketosis
3. Achieve appropriate weight gain
Dr Rania Hussein
43. Screening for diabetes
• Initial screening is done between 24 and 28 weeks of
gestation.
• Rescreening at 32 weeks gestation is recommended
• Screening is done to the following groups:
-25 years of age or older
- <25 years + obese
- Family history of diabetes in first degree
relatives
- If a mother shows any symptoms or signs of
diabetes at any stage of pregnancy.
Dr Rania Hussein
44. Treatment of Gestational diabetes
1. Dietary changes,
2. Moderate exercise
3. Blood glucose monitored daily
Dr Rania Hussein

2 types:
• Gestational hypertension: detected for
the first time after mid pregnancy
• Chronic hypertension: detected before
pregnancy
Dr Rania Hussein
47. Role of diet in preeclampsia:
• Calcium supplementation ↓ BP
• Mg supplements and antioxidants (Vit A and
E) can prevent preeclampsia
• Adequate dietary protein intake to replace the
losses in urine.
Dr Rania Hussein
49. Cigarette smoking
• CO+ Hb= carboxyhemoglobin→↓ available
sites for oxygen binding → fetal hypoxia, and
fetal growth restriction
• ↓ absorption and availability of some nutrients:
vit C, Iron, Zinc, folic acid
Dr Rania Hussein
50. Alcohol consumption
• Alcohol is directly toxic to the embryo and
fetus ( it crosses the placenta, while fetal
organs are still immature)
• The mother is usually undernourished
• It ↓ absorption and utilization of some
nutrients
Dr Rania Hussein
51. Consequences of alcohol
consumption
Fetal alcohol syndrome:
• Mental retardation
• Growth retardation
• Facial abnormalities
• Nervous, cardiac, and genitourinary system
impairment
Dr Rania Hussein
52. Caffeine intake
1. ↑ urinary excretion of Ca and thiamin
2. ↓absorption of Zn and Fe.
3. ↑ heart rate and blood pressure
4. gastric reflux
