Celiac disease: Exploring four myths

While medical knowledge on celiac disease has evolved over the past few decades, there are still aspects that remain poorly understood. Perhaps not surprisingly, misconceptions are widespread among the general public.

Why do I have trouble swallowing?

Common causes of persistent or recurrent swallowing difficulty include medication side effects, an inflamed esophagus, an enlarged thyroid, among others. A doctor can conduct several tests to help identify the problem and offer appropriate treatment.

Can't shake that cough?

The average cough, typically due to a cold or other respiratory virus, lasts three weeks or less. A lingering or chronic cough lasts eight weeks or longer. Most causes of chronic cough aren't serious, such as bronchitis, seasonal allergies, or medication side effects. People should see a doctor if over-the-counter treatments haven't worked or if they experience signs such as breathlessness, wheezing, chest pain, blood in the sputum, weight loss, or fatigue. Before an appointment, people should track their cough and note its patterns to offer clues for diagnosis.

Why does everything taste salty to me?

A variety of factors can make food taste overly salty. These include seasonal or food allergies, medication side effects, gastroesophageal reflux disease (GERD), diabetes, autoimmune conditions, or a chronically dry mouth. People should discuss the problem with their doctor.

Cooling off heartburn

Heartburn usually goes away on its own, but sometimes medication is needed to provide relief. For occasional heartburn, people can use over-the-counter antacids that are magnesium-based, aluminum-based, or calcium-based. If heartburn strikes several times a week or symptoms become more severe, a nonprescription H2 blocker can help. Individuals with persistent heartburn may have gastroesophageal reflux disease (GERD) and will probably need a proton-pump inhibitor. These are available in over-the-counter and prescription versions.

What kinds of cancer screenings should men get as they age?

Of the cancer screening tests for men, tests for colon cancer has the strongest evidence for benefit. Men who opt in for prostate cancer screening may have more options beyond PSA blood testing to more accurately identify aggressive cancers. Other screening tests such as full body scans have not been shown to improve outcomes.

Tattoos may raise lymphoma risks

A 2024 study suggests that having one or more tattoos may raise a person's risk of developing lymphoma, a type of blood cancer.

Should I worry about abnormal Pap test results?

Abnormal Pap test results don't always indicate cervical cancer. Most abnormal findings result from the presence of human papillomavirus, or HPV. Typically, the next step is a colposcopy, a test that enables the doctor to look closely at areas that appear abnormal.
