How much weight will I gain during Pregnancy?

Apparently you can gain from 10 to 20kgs during pregnancy. I know, crazy hey! 

I’d be happy if I only gain 10kgs, but I would need to be eating properly and exercising throughout the pregnancy.

First I need to lose weight and then but it back on through pregnancy.

Oh well, at least I won’t be 94kgs +10kgs= 104kg! That would send me to a mental breakdown seeing myself in the triple digits.

Have a look at this video:

The weight you gain is made up of approximately:

• Baby weighs about 3.3kg (7.3lb).

• Placenta weighs 0.7kg (1.5lb).

• Amniotic fluid weighs 0.8kg (1.8lb).

• The muscle layer of your uterus (womb) grows dramatically, and weighs an extra 0.9kg (2lb).

• Blood weighs an extra 1.2kg (2.6lb).

• Extra fluid in your body, weighing about 1.2kg (2.6lb).

• Bigger breasts weigh an extra 0.4kg (0.9lb).

• Store fat, about 4kg (8.8lb)

So the average weight gain is 12.5kgs, and you should lose around 5kgs on the birth of your child.

BMI and gaining baby weight!
Your body mass index (BMI) measures your weight in relation to your height. It's an accurate way of telling whether or not your weight is in the healthy range. The amount of weight that you should put on in pregnancy depends on what your BMI was before you were pregnant.

• 11.5 to 18kgs if you were a healthy weight before pregnancy, with a BMI of 18.5-24.9.
• 13 to18kgs if you were underweight before pregnancy with a BMI of less than 18.5.

• 7 to 11.5kgs if you were overweight before pregnancy with a BMI of 25-29.9.

• 5 to 9kgs if you were obese before pregnancy with a BMI of over 30.

Carrying a lot of extra weight at the start of pregnancy can increase your risk of complications during your pregnancy and labour, and make you more likely to have:

• high blood pressure

• gestational diabetes

• a big baby (macrosomia)

• a caesarean

Eat a healthy, balanced diet. Women are recommended to have about 2,000 calories a day. You don't need any more than that until the last three months of your pregnancy, when you'll need an extra 200 calories a day.
