You almost never have to fully strip a cast-iron pan.
I've never had to do it, and I've restored some pretty bad pans. Instead of fully stripping it, try just giving it a good hard scrub with soap and steel wool. Scrub what's there down to a level surface (not necessarily all the way back to bare iron) and reseason.
Cooking with cast iron is helpful for preventing low iron but is not an effective standalone treatment for clinically diagnosed anemia. It provides a valuable supplemental boost, especially for vegetarians, but you should rely on prescribed iron supplements or targeted dietary changes to correct a deficiency.

This added iron can naturally supplement your diet, which is especially helpful for preventing or managing iron-deficiency anemia.
For healthy individuals, it is highly unlikely to get iron poisoning from cast iron pans. While the cookware does transfer small amounts of dietary iron into food, the amount is usually small enough to be safe or even beneficial for preventing iron-deficiency anemia.
Iron deficiency occurs when your body lacks enough iron to produce hemoglobin, a protein that helps red blood cells deliver oxygen. Common signs include extreme fatigue, pale skin, shortness of breath, brittle or spoon-shaped nails, and unusual cravings for non-food items (like ice or dirt).

Wear and tear is normal in residential pipe systems. One frequently asked question is “How long do cast iron drain pipes last?” Cast iron waste pipes last anywhere between 50 and 100 years. However, it may be time to replace cast iron pipes long before their lifetime is up.
Yes, Dawn dish soap is perfectly safe for seasoned cast iron. The old rule about avoiding soap stems from decades ago when soaps contained harsh lye, which would strip a pan's seasoning.
