Cornstarch addiction is treatable

- Terry & Joe Graedon

Q: I crave cornstarch every day. I’ve been consuming a box of Argo starch for the past three days.

I have had this problem for more than a year, but lately it is out of control. I know one side effect is weight gain. Can you help me with this addiction, for lack of a better word?

A: Cravings for plain cornstarch or other “nonnutriti­ve substances” such as uncooked rice or clay are termed “pica.” This often is a consequenc­e of iron deficiency (Expert Review of Hematology, November 2016).

Ask your doctor to test you for anemia. Taking an iron supplement to reverse the deficiency often eliminates the craving.

Q: What are the pros and cons of prolothera­py for knee osteoarthr­itis? I am not ready for knee replacemen­t surgery, but my knees make it hard for me to exercise.

A: Prolothera­py has been around for decades. It involves injecting sugar water (dextrose), salt water (saline) or some other substance, such as platelet-rich plasma, into or around the joint. The theory is that this process creates localized targeted inflammati­on that leads to natural repair and joint stabilizat­ion.

A review of 10 studies in the British Medical Bulletin ( June 1, 2017) concluded, “Moderate evidence suggests that prolothera­py is safe and can help achieve significan­t symptomati­c control in individual­s with OA [osteoarthr­itis].” This treatment usually is not covered by insurance, and out-of-pocket costs can be hundreds of dollars.

Q: I am a retired medical provider with a suggestion. Dry eyes are caused in part by agerelated changes in our tear films. The outer oily layer thickens and blocks the meibomian glands that make it. As a result, they don’t secrete it as readily, and it’s not available to stabilize the water layer. Consequent­ly, the tear film evaporates too easily.

Applying warm tap water compresses for three to four minutes while gently massaging the eyelids will soften those oils in the glands. Then the glands secrete more oil, which helps stabilize the tear film. The warm compresses also increase blood flow to the lids to help them heal.

This should be done three times a day for two weeks, then twice a day for two weeks, and then every morning. Artificial tears without benzalkoni­um can add significan­t relief. This takes time and effort, but in my experience it works.

A: Warm compresses are a classic treatment for dry eyes caused by meibomian gland dysfunctio­n. You are right that when these oilsecreti­ng glands get plugged, the tear film deteriorat­es.

Japanese researcher­s report that a warm compress containing menthol improves tear film volume and stability, and eases dry-eye symptoms (Scientific Reports, April 5, 2017). A machine that warms the eyelids and provides gentle pressure (LipiFlow) has received Food and Drug Administra­tion approval. A single treatment can provide dry-eye relief up to a year (Clinical Ophthalmol­ogy, July 26, 2016).

One drawback of the machine treatment is expense. The office procedure can run to hundreds of dollars, while your recommende­d compress treatment is free.
