Be proactive by learning about and tracking your conditions and medications, and by speaking up when you have concerns.

We don't want our golden years to be spent juggling a long list of health issues. But that's the reality for most older adults in the United States.

The CDC reports that 75% of Americans ages 65 or older have several chronic health problems. And a 2013 analysis of Medicare claims published online by Preventing Chronic Disease found that 68% of beneficiaries had two or more chronic conditions and 36% had at least four.

Q. Home remedies aren't stopping my hiccups. Is there something my doctor can prescribe to help?

A. In the May 2018 issue, I answered a question about hiccups, saying they are common but typically short-lived, and that simple home remedies often can end them. However, I ran out of space to say something about treatments for the very unusual cases of hiccups that don't respond to simple treatments.

Q. I understand there's a genetic test that can tell you how well you might respond to antiplatelet drugs. Do you recommend this test?

A. The short answer is no, not yet. For now, I think it is best to wait for the results from studies looking at personalized antiplatelet therapy. Also known as tailored medical therapy, personalized therapy refers to treatments that are based on your own information, including genetics. But first, I will address two other relevant questions: (1) what is antiplatelet therapy, and (2) who needs it?

For people at high risk, PCSK9 inhibitors may prevent heart attacks and save lives. But gaining access to these pricey drugs remains a challenge.

Three years ago, the FDA approved two drugs that lower harmful LDL cholesterol values dramatically 鈥� by more than 50%. The drugs, alirocumab (Praluent) and evolocumab (Repatha), belong to a new category of medications known as PCSK9 inhibitors. Both are given by a self-administered injection once or twice a month.

They're intended for people whose cholesterol levels remain stubbornly high, despite making lifestyle changes (such as diet and exercise) and taking the maximum dose of a high-potency statin and other cholesterol-lowering drugs. In the past two years, results from two large studies found that both PCSK9 inhibitors lowered the risk of serious heart-related events such as heart attack and stroke by 15%.

Newer medications, which may be safer than earlier drugs, have expanded the options for treating obesity.

Obesity is now considered more than a risk factor for other conditions; it's a disease itself. It has been the subject of intense scientific and medical research to develop effective treatments. But the quest has been elusive.

The Surgeon General has issued an advisory recommending that people carry and know how to use naloxone, and although it is an effective treatment for overdose, it does not address the larger issues around the opioid crisis.

Do these heavily promoted hormones justify the claims made for them?

"Bioidentical" hormones have been promoted as safer and more effective than FDA-approved hormones. The exaggerated claims go beyond relief of menopausal symptoms, suggesting they are a veritable fountain of youth.

It's understandable that women would be interested in a different approach now that long-term use of conventional hormone therapy (HT) does not prevent cardiovascular disease as researchers had hoped.

You may need to stop taking blood thinners, certain painkillers, herbs, and supplements to reduce your risk for bleeding.

No one wants to have surgery, even minor surgery, but sometimes minor procedures, such as a tooth extraction or a colonoscopy, are unavoidable. When that happens, you may hear that it's important to stop taking certain medications. Understanding exactly which drugs to suspend 鈥� and when 鈥� can be confusing. "I get a lot of questions about this," says Joanne Doyle Petrongolo, a pharmacist at Harvard-affiliated Massachusetts General Hospital.

Blood thinners

All surgery involves cutting body tissue, and that leads to bleeding. Blood thinners鈥攎edications like anticoagulants and antiplatelet drugs鈥攃an boost the risk for bleeding by keeping the blood from clotting.

Q. I was recently diagnosed with long QT syndrome, which was apparently caused by a medication I was taking. But I understand that there are also genetic causes for this problem. Can you tell me more about this disorder?

A. Long QT syndrome is a rare disorder of the heart's electrical system. Electrical signals coordinate your heartbeat, telling the heart to contract and relax to pump blood. After each beat, the heart's muscle cells are busy recharging themselves for the next contraction by moving sodium, potassium, and calcium through tiny pores on their surfaces.

New medications and side effects warrant an evaluation.

A medication regimen isn't something you can set and forget. You and your doctor need to keep tabs on what you're taking and how it's affecting your health. "We are required to do a medication 'check-up' at every visit, regardless of the specialty, which means that every clinician who sees you is supposed to review your medications and check off a box," says geriatrician Dr. Suzanne Salamon, an assistant professor at Harvard Medical School.

Sometimes things change between visits, and adjustments need to be made. It's up to you to schedule an appointment. Here are seven reasons why that may need to happen.
