How much weight should you gain by 18 weeks pregnant?

Weight gain during pregnancy is dependent on the week of pregnancy you are in.

At 18 weeks of pregnancy, you should increase your weight in the range:

2.8 - 5.0 Kg / 6.1 - 11.0 lbs

Check weight gain in other weeks of pregnancy. Select a week of pregnancy.

During the first trimester of pregnancy, a woman can gain from 0.5 kg to 2 kg (1-4 lbs).

It happens that some women at this stage of pregnancy, instead of gaining weight, lose weight.

This is usually due to frequent nausea and vomiting. However, the weight loss should not be more than 2 kg (4 lbs).

In the second and third trimesters, weight should gain faster, about 0.5 kg (1 lbs) per week.

Weight gain at the end of pregnancy consists of...

ca. 3.5 kg (7.7 lbs) - baby weight
ca. 1-1.5 kg (2.2-3.3 lbs) - uterus
ca. 1-2 kg (2.2-4.4 lbs) - breast 😄
ca. 1-1.5 kg (2.2-3.3 lbs) - amniotic fluid
ca. 0.5-1 kg (1.1 - 2.2 lbs) - placenta
ca. 1.5-2 kg (3.3 - 4.4 lbs) - blood and additional fluids
ca. 2-4 kg (4.4-8.8 lbs) - additional fatty tissue
