DECREASE THE SIZE: Of your 3 main meals. Depending on the carbohydrate meal load, you may be having symptoms of excess Insulin production after meals, which is one of the hallmark chemical and physiologic initial risks of developing diabetes down the road. Please consult this with your doctor. Modifying your diet and exercise should make your symptoms improve or go away, as well as lowering risk for diabetes.

Lots of options: The next step is a visit to the obgyn for an exam, sonogram and blood work. There are medications such as Lysteda which can help. Some will take birth control pills. A sonogram may show a polyp which can be removed. Others are candidates for an endometrial ablation. This is a safe easy option which can be done in a few minutes in the office. I am a fan of the genesys hta ablation.

If the brain does not get enough blood flow, you can pass out and fall.

That means not rubbing the skin with rough clothes, or getting industrial chemicals on them.

Can be other causes: Dizziness with exercise doesn't just happen with inadequate hydration. If a person is well hydrated, and still gets dizzy, her doctor can evaluate. Sometimes there are circulation problems, such as not enough blood flow to the brain under certain conditions or activities. There can be heart problems, or not enough red blood cells (anemia), etc...
