In the first few weeks of pregnancy there may be a slight loss of weight especially if there is any morning sickness. After this passes, weight increase begins, and there is unusually a problem of keeping weight down. Being  overweight puts an extra strain on the pregnant woman. It is much easier to avoid adding pounds during pregnancy than it is to get rid of them afterward. 

Women of normal weight should gain about twenty pounds during pregnancy. Those who are underweight may be put on special diets to gain some permanent pounds, while those who are overweight may be put on reducing diets.

The pregnant woman of average size should consumer about 2,500 calories a day, mainly in meats and other proteins green vegetables and fruits. Starches, fats and sugars are usually restricted. The doctor may prescribe capsules to supply extra iron, and may advise the woman to drink at least a quart of milk a day to provide an adequate supply of calcium. If the woman has a weight problem, skimmed milk may be used since it has the same calcium content. Many doctors also prescribe vitamin pills.

Many women, when pregnant experience acute cravings for certain foods, such as pickles or candy. Eating such foods will do no harm aside from the chance of gaining weight.

If morning sickness occurs it may be helpful to try to ignore it. If this is not effective, the expectant mother might keep some dry crackers or a thermos of weak tea on the bedside table ready to take when she wakes up. After a short rest, she will usually feel ready to get up and eat breakfast. 

Eating small meals frequently perhaps six or seven times a day, with a short rest after each, will also help minimize the effects of morning sickness. Greasy foods, butter, and fats are apt to cause distress as are cucumbers, cabbage, cauliflower, spinach and onions. If these suggestions do not control morning sickness the doctor can help by prescribing medicines.

Most women are no more prone to constipation during pregnancy than they were before. Usually, if it occurs it can be corrected by diet, although irritating bran should be avoided. Fruits and vegetables are recommended as is a glass of cold fruit juice or water before breakfast. 

It is important during pregnancy never to take unnecessary medication. In fact no anti nauseates or other preparations should be taken without the doctor's consent. If X rays should are necessary for any reason, make sure the doctor in charge of taking them is aware of the pregnancy.
