Many women show signs of clumsiness during pregnancy, and more than 25% of pregnant women report falling at least once during their pregnancy. It can be difficult to get used to walking around when your body changes so radically in a relatively short period of time.
What is the reason of this?
As you gain weight and your stomach grows, your center of gravity changes. This can affect your sense of balance. Additionally, pregnancy hormones can loosen your ligaments, so you may feel more prone to falls and clumsiness
Tips
There isn't much you can do to treat vertigo, so the best you can hope for is to manage it. If you have problems with balance, it may be a smart idea to avoid high heels, walking on ice, and other situations where you may be at risk, such as stairs. Comfortable shoes and appropriate lighting can also contribute to a better sense of balance. You should also get up slowly from a sitting or lying position. You should avoid sudden movements and position changes.
