Bisphosphonates: Uses, Types and Side Effects
Bisphosphonates are medicines that slow bone loss and strengthen bones. They're the most common treatment for osteoporosis and also treat Paget's disease.

PEMF Therapy: What Pulsed Electromagnetic Field Therapy Does
Pulsed electromagnetic field (PEMF) therapy is a complementary therapy that uses low-level pulses of electromagnetic energy to try to ease pain, reduce inflammation and support healing. The evidence is mixed, and benefits haven't been proven. It's safe for most people, but not if you're pregnant, have a pacemaker or insulin pump, use a medicine patch or have epilepsy.

Breast Implants: Types, Surgery, Recovery and Risks
Breast implants are silicone shells filled with silicone gel or saline that are surgically placed to enlarge the breasts or rebuild them after mastectomy. You must be at least 18 for saline implants, and the FDA recommends at least 22 for silicone. Full recovery takes six to eight weeks. Implants aren't lifetime devices; they last about 10 years.

Heart Valve Replacement: Valve Types, Procedure and Recovery
Heart valve replacement is a procedure that swaps a diseased heart valve that can't be repaired for a new one. Tissue valves usually last 10 to 20 years and don't need lifelong blood thinners; mechanical valves may last a lifetime but need lifelong warfarin. It can be done with open-heart surgery or a catheter procedure such as TAVR.

Heart Transplant: Who Needs One, Surgery and Recovery
A heart transplant replaces a failing heart with a healthy donor heart. It's a last-resort treatment for end-stage heart failure when other treatments no longer help. The hospital stay is about three weeks, and you'll take anti-rejection medicines for life. About 91% of recipients are alive after one year, and median survival is about 14 years.

Lumbar Epidural Steroid Injection: Uses, Procedure and Results
A lumbar epidural steroid injection (ESI) delivers anti-inflammatory steroid medicine into the epidural space around the spinal nerves in the lower back. It eases sciatica and low back pain caused by irritated nerve roots, most often from a herniated disk or spinal stenosis. Relief can last a few days to a few months. It doesn't cure back pain.

Arthroscopy is a minimally invasive surgery that lets a surgeon see, diagnose and treat problems inside a joint through small incisions, using a thin tube with a light and camera. It's used on the knee, shoulder, hip, ankle, elbow and wrist. Most people go home the same day. It causes less pain and scarring than open surgery.

Breast Lift (Mastopexy): Incision Types, Recovery and Results
A breast lift (mastopexy) is cosmetic surgery that raises and reshapes sagging breasts by removing stretched skin, tightening the remaining tissue and moving the nipple and areola higher. It doesn't change breast size on its own. Surgery takes about one to two hours, and most people go home the same day. Results last several years.

Continuous bladder irrigation (CBI) is a hospital procedure that constantly flushes the bladder with sterile saline while draining urine at the same time.

CBI is generally safe, though it may feel uncomfortable.

Sleeping Pills: Types, How They Work and Side Effects
Sleeping pills (sleep aids, hypnotics) are medicines that make you drowsy and relaxed so you can fall asleep or stay asleep. They're meant for short-term use. Long-term use can cause dependence and rebound insomnia, and older adults face a higher risk of falls. Cognitive behavioral therapy for insomnia (CBT-I) is an effective alternative.

Cardiopulmonary Bypass: How the Heart-Lung Machine Works
Cardiopulmonary bypass (CPB) uses a heart-lung machine to take over the work of the heart and lungs during surgery. The machine adds oxygen to the blood, removes carbon dioxide and pumps it back, letting the surgeon work on a still heart. It's used for most open-heart surgeries. Risks rise the longer you're on the machine.

Deep Brain Stimulation (DBS): Uses, Procedure and Recovery
Deep brain stimulation (DBS) is a treatment that uses a surgically implanted device to send mild electrical pulses to a specific area of the brain. It's FDA-approved for Parkinson's disease, essential tremor and medication-resistant epilepsy. It doesn't cure these conditions, but it can greatly ease symptoms and often allows lower medication doses. It's adjustable and reversible.

They range from store-bought inserts to custom orthotics made from a mold or 3D scan. They're used for plantar fasciitis, flat feet, high arches and bunions. They manage symptoms but don't cure the underlying problem.

ACE inhibitors (angiotensin-converting enzyme inhibitors) are medicines that relax blood vessels and lower blood pressure by blocking a hormone called angiotensin II.

CPAP Machine: How It Works, Masks and Side Effects
A CPAP machine (continuous positive airway pressure) treats obstructive sleep apnea by blowing a steady stream of air through a mask while you sleep. The gentle pressure keeps the airway from collapsing. It's often the first treatment for sleep apnea and is very effective when used every night. Benefits include better sleep, less snoring and less daytime sleepiness.

Pain Management: Types, Treatments and What to Expect
Pain management uses medicines, procedures, exercise, therapy and lifestyle changes to prevent, reduce or relieve pain and help you function better. It treats both acute pain, such as after an injury or surgery, and chronic pain that lasts months or years. Opioids are generally avoided when possible. The goal is better daily life; complete relief isn't always possible.
