Many reasons: Nicotine itself is toxic to the heart, and elevates heart rate, which makes the heart work harder. It lowers the oxygen level in blood, raises carbon monoxide levels (which further steals oxygen from our cells), adds poisons such as formaldehyde into the body), and anything that damages the lungs will damage the heart as well. You don't need to know why, you need to know it does, and to stop!

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.

Poor blood flow: The balance centers of the brain depend on good blood flow to the brain. If the heart is beating slowly or is not pumping enough blood into the brain, you will feel dizzy. First is to lie down so that the blood flow does not have to go uphill. Next is to lift the legs to be sure enough blood is getting into the heart. If the brain does not get enough blood flow, you can pass out and fall.

May be hard to do...: People try to live and work in conditions that their bodies are able to adapt to, but sometimes that is not possible.

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...
