Insomnia is a sleep disorder where falling asleep, staying asleep, or getting restful sleep becomes difficult, despite having the chance to rest. It’s more than just the occasional bad night. It leads to next-day problems such as fatigue, low mood, poor concentration, or feeling mentally slowed down.

T2D occurs when the body cannot properly use insulin, or when the pancreas does not make enough insulin to keep blood sugar levels in balance.

Elevated LDL allows excess cholesterol to seep into the lining of your arteries. Over time, this mixes with fats, calcium, and inflammatory cells to form plaque. Plaque narrows and stiffens arteries, restricting blood flow to vital organs like your heart and brain.

LDL levels below 55 mg/dL is a very low number and often requires high doses of multiple medications. The new goal (below 70 mg/dL) is no longer just to hit the lowest number possible, but to find the "sweet spot" where you get the most protection with the fewest side effects and costs.

Non-celiac gluten sensitivity (NCGS) is a condition where people experience uncomfortable symptoms after eating foods containing gluten. Unlike celiac disease or wheat allergies, NCGS doesn't damage the intestines or involve an allergic reaction.

Heart health thrives on balance. Choosing unsaturated fats over saturated ones, eating more fiber-rich plant foods, and keeping up with regular aerobic activity all reinforce one another.

Higher HDL-C is more than just a number on a blood test. Evidence shows that higher levels are linked to less plaque buildup in the arteries and a lower risk of major events like heart attacks.

Spironolactone, also known by its brand name Aldactone, has been approved by the FDA since 1960 and is widely used for various medical conditions. It belongs to a class of medications called potassium-sparing diuretics, often referred to as “water pills.”

Zypitamag is not primarily metabolized by CYP3A4. Instead, it is mainly processed through UGT enzymes, a less busy pathway that grapefruit does not interfere with. This dramatically reduces the risk of food–drug interactions.

Probiotics are live bacteria that add to the population of good microbes in your gut, while prebiotics are the food that helps those beneficial bacteria grow and thrive. Think of it as planting a garden—probiotics are the seeds, and prebiotics are the fertilizer.

Thyroid levels represent a snapshot in time. Looking at patterns over multiple tests gives a clearer picture. Sharing this full context with your healthcare provider helps guide more accurate decisions and avoids unnecessary confusion.

Decongestants target this swelling directly by constricting the enlarged blood vessels in the nasal passages. This opens up the airways for easier breathing and can also reduce sinus pressure. They come in two main forms: oral (tablets or liquids) and nasal sprays.

Levothyroxine remains the preferred first-choice treatment for hypothyroidism. It's effective, stable, and safe for most people, backed by decades of evidence and guidelines. Liothyronine (alone or added to levothyroxine) can help some with lingering symptoms, but it requires specialist oversight due to faster action and monitoring needs.

Each year, nearly 1 in 4 adults in the United States suffer from seasonal allergies. If you're one of them, you're likely familiar with the relentless sneezing, itchy eyes, and runny nose that allergens like pollen, dust, and pet dander can trigger. For millions, antihistamines are a go-to solution, with popular choices like Benadryl, Zyrtec, and Claritin offering relief. But not all antihistamines are created equal.

Certain antidepressants—those with sedating properties—may be prescribed for sleep issues, particularly when insomnia occurs alongside depression or anxiety. These include medications like trazodone, mirtazapine, and amitriptyline.

For most children and adults, RSV feels like a regular cold, with symptoms like runny nose, cough, and maybe a mild fever. But RSV can sometimes cause more serious illness, especially in babies and older adults.

Tonsillitis is inflammation of the tonsils, while strep throat is a specific bacterial infection that can lead to tonsillitis.

Neffy is the first epinephrine nasal spray for treating severe allergic reactions, including anaphylaxis. It was developed by ARS Pharmaceuticals and offers a needle-free alternative for people who need fast relief during an allergic emergency.

Cold weather can be tough on your skin. As temperatures drop and humidity levels fall, your skin loses moisture more quickly, making it feel dry, tight, and sensitive.

In October 2025, more than half a million bottles of the blood pressure drug prazosin were pulled from shelves after tests revealed nitrosamine impurities. It wasn’t the first time, and likely won’t be the last.
