Many products make claims that are untrue. You can waste a lot of money or, worse yet, do yourself harm by taking medications or other treatments without the approval of your own doctor. Two medications used commonly by the elderly are laxatives and aspirin. Habitual use of laxatives may decrease absorption of minerals such as calcium and potassium. Potassium may be a particular concern if you are taking certain kinds of medicine for high blood pressure.
Mineral oil can decrease absorption of fat-soluble vitamins.
Aspirin is often prescribed to relieve arthritis pain. Sometimes aspirin may cause bleeding in the stomach which could lead to iron deficiency. Check with your doctor or pharmacist if you take these medications regularly. Another common problem is the loss of teeth and coping with dentures. Fifty percent of people over age 60 have lost all their teeth.
