Morning Sickness

Nausea is one of the most common – and most miserable – complaints of pregnancy, affecting around 70 per cent of pregnant women. It is often referred to as morning sickness, and for some women occurs only in the morning, but it can occur at any time during the day. Some women just feel sick; others actually vomit.
There are different theories about what causes morning sickness. Hormonal changes, changes in blood pressure and changes in your digestive system may all play a part. There is also a theory that morning sickness may help prevent any harmful toxins in your diet getting through to your baby. Tiredness can make feelings of nausea worse but won’t actually cause it.
Morning Sickness signs
Morning sickness is one of the earliest signs that you are pregnant, and nausea can begin as early as a few days after you have missed your period. In the majority of cases, it tails off between three and four months, though in some cases it can persist throughout pregnancy. If this happens, especially if you are vomiting a lot, consult your doctor. Severe vomiting may require hospital treatment.
Although morning sickness can make you feel wretched, it won’t harm your baby. In fact there is evidence that if you suffer from it, you may be less likely to have a miscarriage. Rarely, morning sickness can develop into hyperemesis gravidarum which is an excessive form of morning sickness.
