What Is an Acute Illness?
An acute illness is a sudden-onset health condition that develops quickly, often within a short period. Unlike chronic conditions such as diabetes or high blood pressure, which last an extended span of time, acute illnesses appear rapidly and typically resolve with proper treatment.
These conditions may last days or weeks, but their symptoms often require timely evaluation. Symptoms may get worse quickly without timely care. When your health changes suddenly, a same-day medical evaluation can help prevent complications.
If your symptoms appeared suddenly, call us today for immediate evaluation.

How Do We Diagnose Acute Diseases and Rapid-Onset Conditions?
We begin with a clear conversation about your symptoms, when they started, and how they've changed. Your doctor may perform:

- Point-of-care testing (flu, strep, COVID-19)
- Bloodwork
- Imaging for acute injury or broken bones
- Medication review
- Vital sign monitoring
Our goal is to identify the cause of your illness, understand its severity, and offer an immediate plan to treat your condition.
Treatment Options for Acute Illnesses
Your treatment depends on your symptoms and diagnosis. Care may include:
- Medications
- Antiviral or antibiotic drugs, when appropriate
- Pain relief medicine
- Hydration therapy
- Complementary treatments (based on your health condition)
- Lifestyle changes to support recovery
- A short-term health care plan
- Follow-up visits if needed
We explain what to expect during recovery and provide clear instructions for managing symptoms at home.

When to Visit the ER Instead of Primary Care?
Primary care can address most acute illnesses, but certain symptoms require emergency care. Visit the ER if you experience:
- Chest pain
- Uncontrolled bleeding
- Trouble breathing
- Sudden vision loss
- Head injury
- Signs of stroke
- Severe dehydration
If your condition can be safely managed here, we keep your care close to home and help reduce unnecessary hospital visits.

How to Reduce Your Risk of Acute Illness?
Small daily habits can make a meaningful difference:
- Wash hands often
- Avoid smoking
- Maintain a healthy weight
- Stay physically active
- Make balanced food choices
- Manage sun exposure (limit long outdoor periods during peak hours)
- Stay hydrated
- Address chronic illness early to prevent flare-ups
- Get enough sleep
Practicing these habits regularly helps reduce your risk of sudden illness and supports long-term health, especially as you get older.
