Diarrhea

Diarrhea is almost always the body dealing with a temporary irritant or infection — here's what typically causes it, how to treat it at home, and when it points to something that needs attention.

Food Poisoning

Food poisoning usually strikes within hours of eating contaminated food and clears up on its own within a few days — here's how to spot it, treat it, and know when it's more serious.

Gastroenteritis

Often called the 'stomach flu,' gastroenteritis is usually viral, highly contagious, and resolves on its own — the main risk to manage is dehydration, not the infection itself.

COVID-19

COVID-19 today looks different than it did in 2020 — for most vaccinated, healthy people it's a manageable illness, but knowing current symptoms, contagious periods, and risk factors still matters.

RSV (Respiratory Syncytial Virus)

RSV causes mild cold-like symptoms in most people but can be genuinely serious for infants and older adults — here's how to recognize the difference.

Pneumonia

Pneumonia can range from a manageable illness treated at home to a genuine medical emergency, especially for young children, older adults, and people with weakened immune systems.

Bronchitis

A lingering cough after a cold is often acute bronchitis — usually viral, not needing antibiotics, but sometimes confused with pneumonia when symptoms are severe.

Ear Infection

Ear infections are especially common in young children and usually improve within a few days — here's what causes them and when antibiotics or a doctor's visit are actually needed.

Tonsillitis causes a sore throat plus visibly swollen, often white-coated tonsils — usually viral, but frequent recurrence can raise the question of removing the tonsils altogether.

Sore Throat

Most sore throats are caused by common viruses and clear up on their own — here's how to tell a viral sore throat from one that needs a doctor's visit, and whether it's contagious.

Common Cold

The common cold is the most frequent human illness, usually mild and self-limited — here's what to expect, how to feel better faster, and when it might be something more.

Influenza (Flu)

The flu comes on faster and hits harder than a common cold, and can be genuinely dangerous for some groups — here's how to recognize it, treat it, and know when it needs medical attention.

Treatment for H. pylori

H. pylori is treated with a combination of medications taken together for one to two weeks — here's how treatment generally works.

Symptoms of H. pylori Infection

Most H. pylori infections cause no symptoms — but when they do, here's what to watch for, and the warning signs that need urgent care.
