Considering nose strips and other nighttime congestion aids

DEAR DR. ROACH >> I have allergies and am congested a lot at night. I have read about overthe-counter clips and adhesive tapes. Would they help me breathe better? Are they safe? — M.V.M.

DEAR READER >> There are many types of external devices designed to open the nasal passages during sleep to make breathing easier. Some of them are more like adhesive tape; others are inserted into the nostrils. They are marketed for nighttime use and to improve sports performance.

A few years ago, a review of studies on safety and effectiveness on these devices showed modest effectiveness, with as much as 75 percent improvement in symptoms. However, reviews at an online retailer were decidedly mixed. I believe a person’s anatomy may be suited to only a particular type of device, or perhaps none at all. Fortunately, these devices are relatively inexpensive and safe, and may have significant benefit, so it may be worth a try. They almost certainly are safer than medication.

DEAR DR. ROACH >> Iama 79-year-old woman, recently diagnosed with fatty liver. When I asked what to do about it, I was told to eat more fiber. No one gave me a suggested eating plan to help me do this. My present weight is 221 pounds, and I am 5 feet, 5 inches tall. I take oxcarbazepine for epilepsy and amlodipine for high blood pressure. I was never a drinker, just an occasional drink on a special occasion. Otherwise I am an active senior. — J.M.

DEAR READER >> Fatty liver, in people who do not drink excess alcohol, is a spectrum of disease. It ranges from mild enlargement of liver with fat to inflammation of the liver. This last can lead to fibrosis of the liver and eventually cirrhosis.

The best treatment for NAFLD is a change in diet. Fiber certainly is one important component. The optimal diet for someone with NAFLD is similar to that for a person with diabetes, and any registered dietician nutritionist would be able to help you with that. And vitamin E may help.
