So, in order to eliminate excess lactic acid, vomiting occurs.

10. Pregnancy

Nausea is one of the first symptoms of pregnancy and is usually present from the 6th week of pregnancy. Vomiting is one of the main symptoms experienced by pregnant women and most often occurs in the morning. Nausea in pregnancy usually does not result in vomiting, but should be reported to the obstetrician if it is frequent. 

Vomiting craving and nausea during pregnancy, when in excess, is a condition called hyperemesis gravidarum, which may require hospitalization and hydroelectrolytic treatment, because the physician should not indicate the use of antiemetics before the 12th week of gestation.

11. Hypoglycemia

Hypoglycemia can be defined as a decrease in blood glucose levels, producing symptoms such as dizziness or vertigo, lack of coordination and nausea, the main cause being too much insulin in the body.

In case of nausea, it may be recommended you use some medication that can help relieve the nausea, such as Bromopride, Metoclopramide or Domperidone, for example, which should be used under medical advice. 

In addition to the use of medication, it is recommended you avoid consuming very fatty or heavy foods, as they make digestion difficult and may cause nausea, drink plenty of water, which can be taken with a few drops of lemon, for example, and drink teas, as they may decrease the vomiting sensation, such as mint tea and ginger tea.
