As we age, our bodies change, and certain health conditions become more common. Understanding these conditions and their symptoms can help seniors and caregivers manage health concerns more effectively. Whether it’s recognizing early warning signs or simply feeling more confident when talking to your doctor, knowing these terms can make a big difference.

• Arthritis—A condition that causes pain, stiffness, and swelling in the joints. It can make movement difficult, especially in the hands, knees, and hips.
• Chronic obstructive pulmonary disease (COPD)—A long-term lung disease that makes breathing difficult. It includes conditions like emphysema and chronic bronchitis and often causes coughing, wheezing, and shortness of breath.
• Dementia—A group of brain conditions that affect memory, thinking, and decision-making. Alzheimer’s disease is the most common type. Dementia can make daily tasks and conversations challenging.
• Diabetes—A condition that affects how the body processes sugar (glucose). It can cause high blood sugar levels, leading to problems like fatigue, frequent urination, and slow healing of wounds.
• Hypertension—Also known as high blood pressure, this condition forces the heart to work harder to pump blood. It can increase the risk of heart disease and stroke but often has no symptoms.
• Osteoporosis—A condition that weakens bones, making them more likely to break. It’s more common in older adults, especially women, and can lead to fractures from even minor falls.

• Anemia—A condition where the body doesn’t have enough healthy red blood cells, leading to fatigue, weakness, and pale skin. It can be caused by low iron levels or other health issues.^·2
• Delirium—A sudden change in thinking and awareness, often causing confusion, restlessness, or hallucinations. It can be triggered by infections, medications, or dehydration.
• Edema—Swelling caused by excess fluid buildup, often in the legs, ankles, or feet. It can be a sign of heart, kidney, or liver problems.³
• Incontinence—The inability to control urination or bowel movements. It’s common in older adults and can be managed with lifestyle changes, medications, or medical devices.
• Vertigo—A sensation of dizziness or feeling like the room is spinning. It can be caused by inner ear problems or other medical conditions.

Medications and treatments play a key role in managing health as we age. However, the terms used by doctors and pharmacists can sometimes be confusing. Understanding these words can help seniors and caregivers make informed decisions about care and treatment options. 

• Contraindication—A reason why a certain medication should not be used. For example, some drugs are unsafe for people with specific allergies or health conditions. ⁴
• Dosage—The amount of medication a person should take at one time. Dosage instructions include how much, how often, and when to take that medicine.
• Generic drug—A medication that has the same active ingredients as a brand-name drug but usually costs less. Generic drugs work just as well as their brand-name versions.
• Over-the-counter (OTC) drugs—Medicines that can be bought without a prescription, like pain relievers, allergy medicine, and antacids. They are safe when used correctly but can still interact with other medications.
• Side effect—An unexpected reaction to a medication. Side effects can be mild, like drowsiness, or more serious, like nausea or dizziness. Always report severe side effects to your doctor.

• Hospice care—Special care for people in the final stages of a serious illness. Hospice focuses on comfort and quality of life rather than curing the illness.
• Immunization—Also called a vaccine, this treatment protects against diseases like flu, pneumonia, and shingles. Immunizations help seniors stay healthy and prevent infections.
• Occupational therapy—Therapy that helps people regain skills for daily activities, like dressing, cooking, or using their hands after an injury or illness.
• Palliative care—Care focused on relieving pain and discomfort for people with serious illnesses. Unlike hospice, palliative care can be given at any stage of an illness, not just at the end of life.
• Physical therapy—Exercises and treatments that help improve movement, strength, and balance after an injury, surgery, or illness.
• Speech therapy—Treatment to help with speech, swallowing, and communication problems caused by stroke, dementia, or other conditions.

Healthcare costs can be confusing, especially with all the different insurance terms and financial decisions involved in senior care. Understanding these terms can help seniors and caregivers manage expenses and avoid unexpected costs.

• Co-pay—A fixed amount you pay for a medical service or prescription. For example, a doctor’s visit might have a $20 co-pay, while a specialist visit could cost more.
• Coinsurance—The percentage of costs you share with your insurance after meeting your deductible. If your coinsurance is 20%, you pay 20% of the bill and insurance covers the rest.
• Deductible—The amount you must pay out of pocket before your insurance starts covering costs. A higher deductible usually means lower monthly premiums but more upfront expenses.
• Explanation of benefits (EOB)—A document from your insurance company that shows what medical services were billed, how much was covered, and what you may owe. It is not a bill, but it helps track healthcare expenses.
• Medicaid—A government program that provides free or low-cost healthcare for eligible low-income individuals, including some seniors who need long-term care.⁵
• Medicare—A federal health insurance program for people 65 and older or those with certain disabilities. It includes different plans that cover hospital stays, doctor visits, and prescriptions.⁶
• Premium—The amount you pay each month for health insurance, whether you use medical services or not. Higher premiums often mean lower out-of-pocket costs for care.

• Estate planning—The process of organizing assets, wills, and healthcare wishes to ensure your property and money are handled according to your wishes after you pass away.
• Living will—A legal document that details your medical preferences if you become unable to make decisions, such as whether you want life-support treatments.⁷
• Power of attorney (POA)—A legal document that allows a trusted person to make financial or healthcare decisions on your behalf if you become unable to do so.⁸
• Trust—A legal arrangement that holds and manages assets for beneficiaries. Trusts can help protect finances, reduce taxes, and ensure assets are distributed according to your wishes.

As seniors age, their care needs may change. Whether living independently, receiving help at home, or moving to a specialized facility, understanding the different care options and support services available can make planning easier for both seniors and caregivers.

• Adult day care—A daytime program that provides social activities, meals, and sometimes medical care for seniors who need supervision while their caregivers are at work or need a break.
• Assisted living—A residential community where seniors receive help with daily tasks like bathing, dressing, and medication management while still maintaining some independence.
• Home care—Support services provided in a senior’s home, including help with daily activities, housekeeping, and sometimes medical care from nurses or therapists.
• Independent living—A housing option for seniors who are still active and able to care for themselves but prefer a community setting with amenities like meal services, housekeeping, and social activities.
• Nursing home—A facility that provides 24-hour medical care and assistance for seniors with serious health conditions who need ongoing supervision and support.
• Rehabilitation center—A short-term care facility that helps seniors recover after surgery, injury, or illness through physical therapy, occupational therapy, and medical supervision.
• Senior center—A community space offering social activities, educational programs, exercise classes, and resources to help seniors stay active and engaged.

• Caregiver support groups—Groups where caregivers can share experiences, get advice, and receive emotional support from others who understand the challenges of caring for a senior loved one.
• Geriatric care manager—A professional who helps families coordinate senior care, manage medical needs, and navigate financial and legal decisions.
• Respite care—Temporary care that gives primary caregivers a break, whether for a few hours, a day, or even longer. It can be provided at home or in a facility.

When it comes to senior care, legal and ethical decisions play a crucial role in protecting a person’s rights, privacy, and dignity. Understanding these terms helps seniors and caregivers make informed choices about medical care, legal responsibilities, and personal wishes.

• Advance directive—A legal document that outlines a person’s healthcare wishes if they become unable to communicate. This can include decisions about life support, resuscitation, and organ donation.7
• Conservatorship—A legal arrangement where a court appoints a person to manage someone’s financial or personal affairs if they are no longer able to do so themselves.
• Guardianship—Similar to conservatorship, but broader. A guardian is responsible for making legal, financial, and medical decisions for someone who can no longer care for themselves.
• Health Insurance Portability and Accountability Act (HIPAA)—A law that protects a person’s private medical information. It ensures that doctors, hospitals, and insurance companies cannot share health records without permission.⁹

• End-of-life decisions—Choices about medical care at the final stage of life, including whether to receive life-prolonging treatments, hospice care, or pain management.
• Informed consent—The process of understanding and agreeing to a medical treatment or procedure after a doctor explains the risks, benefits, and alternatives.
• Patient autonomy—A person’s right to make their own healthcare decisions, even if their choices differ from what family members or doctors might prefer.

Navigating senior healthcare can feel overwhelming, but understanding key terms can make a big difference. Hopefully this guide will give you the context needed to communicate more effectively with doctors and reduce stress when it comes to healthcare decisions. With the right knowledge, you can confidently navigate the healthcare system and make the best choices for yourself or your loved one.
