Numb feet during exercise may come from a number of causes. If you are experiencing numb feet and toes during a workout on the elliptical, it may be due to injury, poor circulation due to illness, or ill-fitting shoes. It is best to determine the cause of your numbness so that you can take the appropriate measures to prevent the numbness from reoccurring.
Most Common Causes
Numbness on any body part usually occurs from being in one position for a long period of time, notes MedlinePlus. Most commonly, foot or toe numbness during exercise comes from wearing shoes that are too tight; this prevents your foot from moving around in your shoe and can mildly cut off circulation to the foot. You may try loosening your shoelaces before exercising or buying a larger pair of shoes to give your feet room to move and breathe.
Diabetes
One of the most common symptoms of diabetes is numbness of the extremities. Diabetes is often caused by having too little insulin in the body or because of an individual's resistance to insulin. Along with numbness, individuals may also notice blurry vision, excessive thirst, fatigue, frequent urination, hunger and weight loss. If you think you might be diabetic, see your doctor to get the appropriate treatment.
Other Causes
Common causes of numbness include having abnormal levels of vitamins and minerals such as calcium, potassium or sodium in your body. A less likely cause of numbness may be Morton's neuroma, which is a noncancerous growth of nervous tissue, according to FamilyDoctor.org. Over-the-counter medication and ice massages can relieve discomfort. Other possible, but less likely causes include underactive thyroid, stroke and reactions to medication or radiation therapy.
Treatment
If you experience numbness while using the elliptical and it has become bothersome or painful, you may need to see your medical professional as it is possible that it is a sign of another illness. In most cases, simple adjustments to your shoes can be made. But if the cause is elsewhere, the appropriate measures should be taken to prevent a more severe condition from arising. Your doctor may recommend medications or vitamin supplements to relieve uncomfortable and persistent numbness.
