What is thirst in early pregnancy?

I have just been pregnant for half a month, and I always feel very thirsty during this period. I would like to know what is the reason for thirst in the first trimester?

The reasons for thirst in early pregnancy are as follows: 1. Most pregnant women will have different degrees of early pregnancy reactions in the early stage, such as nausea, vomiting, loss of appetite, etc. If the frequency of nausea and vomiting is high, It will cause the body to lose water faster, which will cause discomfort symptoms such as thirst. 2. Some pregnant women are prone to negative emotions such as anxiety or tension in the early stage. Causes the sympathetic nerves to remain in a state of excitement, and symptoms such as thirst appear. Pregnant women should carefully observe their own conditions at ordinary times, and replenish water in time when they are thirsty to avoid dehydration or electrolyte imbalance.
