Can Morning Sickness Start At 8 Weeks?

Morning sickness is the most common symptom in pregnancy. It is so common that in most of cases, the pregnancy is detected through the symptoms of morning sickness. The cause of morning sickness is primarily the alteration of the hormonal level to the intolerable limit which can occur at any stage of pregnancy.

Can Morning Sickness Start At 8 Weeks?

Can Morning Sickness Start At 8 Weeks?

Morning sickness can start at 8th week. The symptoms of morning sickness develop at 3rd to 7th week of pregnancy and reach its severity at 10th week. From 14th week, the symptoms start reducing.

Complications Of Morning Sickness

Various complications, both to the fetus as well as the mother, may occur if morning sickness is not effectively managed. The complications are more severe in hyperemesis gravidarum. Following are the complications of morning sickness:

Dehydration. As the frequency of vomiting increases, the patient suffers from dehydration. This results in cardiac palpitations and reduced frequency of urination.

Electrolytic Imbalance. The vomiting cause’s dehydration i.e. the water level inside the body reduces, leading to altering the concentration of electrolytes. The electrolytes perform vital functions and required in normal concentration for optimum functioning.

Nutritional Deficiency. Whatever the patient eats, comes out through the forceful discharge from the mouth, it may lead to nutritional deficiency. In the conditions of hyperemesis gravidarum, the patient requires intravenous infusion to provide nutrition as well as electrolytes.

Muscular Pain. Vomiting is a muscular activity that requires the powerful emetic action of stomach muscles. Frequent vomiting leads to pain in the stomach muscles that also add to the discomfort of patients.

Increased Stress And Anxiety. Unmanaged morning sickness symptoms increase the symptoms of anxiety in the patient and the patient may be under emotional stress.

Metabolic Imbalances. Metabolic symptoms such as ketoacidosis and thyrotoxicosis may also develop in patients with poorly managed hyperemesis gravidarum.

Stages Of Morning Sickness

As the hormonal level stars faltering, the symptoms of the morning sickness start developing. Thus, more alteration in the hormonal level leads to more severe hormonal symptoms. Following are the various stages of morning sickness.

Mild Morning Sickness Or Early Stage. The early stages of the morning sickness do not cause many symptoms rather the patient feels slightly uncomfortable. The patient feels slightly fatigue and required to do rest. The patient feels slightly nauseous and starts feeling discomfort in the stomach.

Moderate Morning Sickness. At this stage, the women feel the symptoms of morning sickness almost every day. The patients develop other symptoms such as low appetite, reduced weight, and irritability.

Severe Morning Sickness Or Advanced Stage. The severe condition of morning sickness leads to vomiting at least two times per day and on almost every day. The condition is known as hyperemesis gravidarum. The condition, if left unmanaged, may lead to dehydration, electrolytic imbalance, metabolic disorders, and stress.

Developing Morning Sickness

Morning sickness is a common condition found during pregnancy. Some researchers believe that women having morning sickness are at low risk for miscarriage as compared to women with no morning sickness. The morning sickness may develop at any time during pregnancy; however, commonly the morning sickness starts during 3rd to 7th week of pregnancy. At the 8th week of pregnancy, the severity of the morning sickness increases. The severity starts decreasing from the 10th week and by 12th to 14th week the women may be relieved with the symptoms of morning sickness. It has been estimated that almost 75% of the women develop morning sickness during the first trimester out of which half have the symptoms of vomiting.

Women after 20 weeks of pregnancy can also develop morning sickness. The hormone level in the body is highest during 3rd to 10th week of pregnancy which is regarded as the most important cause of morning sickness. The symptoms subsided after a 14th week due to a reduction in the hormonal levels and the adjustment by the body against increased hormonal levels. In most cases of pregnancy, the pregnancy is detected through the morning symptoms, as the condition may develop much before the pregnancy test has been done.
