In the first trimester, don't wait until you're hungry to eat. Have nutritious snacks every three hours. Low-fat cheese and crackers or fruit and yogurt may help you bridge the gap between meals and avoid nausea. Your increased blood volume requires extra fluids to prevent dehydration, which can lead to fatigue. Add fibre to your diet.
Irregularity is common and can be due to the pregnancy itself or a result of prenatal supplements.
Opt for fibre-rich foods such as whole grain breads and cereals along with a variety of raw or cooked fruits and vegetables. While you get plenty of vitamins and minerals drinking vegetable and fruit juices, you're not getting any fibre. Watch your calcium intake. Without adequate calcium, the fetus's skeletal development will home in on your body's own calcium stores, sapping the mineral from your bones and teeth. You need the calcium equivalent of three to four glasses of skim or 1 percent milk a day.
