وحم الحوامل حقيقة أم وهم !!!

Quote: Morning Sickness Causes Unfortunately, no one is exactly sure what causes morning sickness but it would seem that the cause is a combination of issues related to the chemical changes your body is going through. Those changes include rapidly increasing estrogen and progesterone levels, an enhanced sense of smell and excess stomach acids. It has also been suggested that stress and fatigue that commonly accompany pregnancy also play a role. One of the theories is that morning sickness is caused by the dominant hormone during pregnancy, progesterone. Progesterone has a "softening" effect on the muscles in the body. It is thought it helps prevent preterm labor by effecting the uterine muscles. It also effects other muscles, such as the stomach and intestines. The progesterone relaxes the workings of the whole digestive track which makes the elimination of bodily wastes slower which can lead to a slow emptying of the stomach which leads to excess stomach acids. Another theory, and more widely accepted, is that morning sickness is caused by the buildup of hCG (human chorionic gonadotopin) in your system. hCG is produced after implantation takes place and continues to increase until about the 12th week of your pregnancy, at which point the levels of hCG starts to decrease. If you are lucky, this is when your morning sickness symptoms will start to decrease as well. Morning sickness isn't all bad though. Recent studies have suggested that mothers who have morning sickness have fewer miscarriages so there IS a bright spot in the midst of your morning, or in some cases, all day miseries.

Quote: Morning sickness and nausea during pregnancy Reviewed by Dr Philip Owen, consultant obstetrician and gynaecologist In the first half of pregnancy, feeling sick or nauseated is quite common, as is vomiting. The degree of nausea and vomiting differs from woman to woman. You may just feel a little sick in the morning and throw up once, or your may suffer from constant nausea and frequent vomiting throughout the day. For most women, the nausea stops after the first three months of pregnancy. For a few, however, it is still a problem after four or five months. What causes nausea during pregnancy? The actual causes of nausea and vomiting are still not known. It is probably brought about by the hormonal changes taking place or by an imbalance in blood sugar. Many midwives and doctors believe that morning sickness is more common in women carrying twins or triplets, but it is not clear whether this is the case. Symptoms of dehydration Dizziness. Thirst. Passing a smaller amount of urine than usual or none at all. Passing dark urine. The presence of ketones in your urine. Your midwife or GP can easily test this. Is it dangerous? If you vomit heavily and often when pregnant, you will lose so much liquid (together with nutrition and minerals) that it causes dehydration. If you are dehydrated and can't keep liquids down, the condition is called hyperemesis gravidarum and requires medical attention. This usually involves hospital admission and being given fluids through a drip. How can I avoid nausea? In the morning Take your time getting out of bed. If you tend to feel really sick in the morning, eat a little as soon as you wake up and before getting out of bed. Ask your partner to bring the food to you, or prepare a snack the night before and leave it beside your bed. Throughout the day Eat little and often, every two or three hours - even if you're not hungry. Drink a lot of liquid, preferably 10 to 12 glasses of water, fruit juice or herbal tea each day. Avoid food containing a lot of fat or spices. Avoid alcohol and caffeine. Eat dry crackers, toasted bread or rusks. Ginger tea or ginger tablets can help reduce nausea. Rest several times a day. Lie down with a pillow under your head and legs. Move slowly and avoid sudden movements. After eating, sit down so that gravity helps to keep the food in your stomach. Avoid smells that make you feel sick or throw up. Don't brush your teeth immediately after eating because this can cause vomiting. Get some fresh air and exercise by going for a little walk every day. Avoid smoking. Not only is it harmful for you and your child, it also diminishes your appetite. At night Before going to bed, it may help to eat a snack such as a yoghurt, bread, milk, cereal or a sandwich. If you wake up during the night, eating a small snack may stop you feeling sick in the morning. Sleep with the windows open to get some fresh air, if possible. When should I consult my doctor? If none of the remedies mentioned above seem to work. If you vomit more than three or four times a day. If you lose weight. If your vomit contains blood or looks like ground coffee. If you lose more liquid than you can keep down. If you are dehydrated (see box above). If you are worried about your condition, or believe that something serious is the matter. What will the doctor do? The doctor will examine you for signs of dehydration. A simple urine test (ketone test) is often helpful in deciding the degree of dehydration. Anti-sickness tablets can be prescribed. Your doctor will be careful to ensure you are prescribed medication that does not harm your baby.
