Can a Sinus Infection Cause High Blood Pressure?

If you've noticed your blood pressure rising during a sinus infection, you're not imagining things. Research shows there can be a connection. Let's break down exactly how sinus problems might affect your blood pressure and when you should be concerned.

How Sinus Infections Can Affect Your Blood Pressure

1. Sinus Infections Put Stress on Your Body

When you have a sinus infection, your body is busy fighting inflammation and infection. This triggers stress responses that can temporarily raise blood pressure. Here’s why:

• Pain and Discomfort: Chronic sinus pressure and headaches can increase stress hormones like cortisol, which may push your blood pressure up.
• Poor Sleep: Sinus congestion often interrupts your sleep, and not getting enough rest is linked to higher blood pressure.
• Medication Side Effects: Some common decongestants, like pseudoephedrine, narrow blood vessels and can raise blood pressure, especially if you’re already at risk

2. Chronic Sinusitis and Long-Term Blood Pressure Risks

A one-time sinus infection might cause only a temporary bump in blood pressure, but chronic sinusitis (lasting 12 weeks or more) possibly has longer-lasting effects.

• Studies have found that people with chronic sinusitis may face a higher risk of cardiovascular problems, including hypertension, likely due to ongoing inflammation.
• Research also suggests that chronic sinus inflammation might contribute to endothelial dysfunction —a condition affecting blood vessels and linked to high blood pressure.

3. Decongestants and Blood Pressure Concerns

Many over-the-counter (OTC) sinus medications contain pseudoephedrine or phenylephrine, which can raise your blood pressure by constricting blood vessels.

• The American Heart Association recommends people with high blood pressure use decongestants cautiously, as they may worsen hypertension.
• A 2005 study showed that pseudoephedrine increased blood pressure in some patients, especially those already at risk.

If you have high blood pressure, safer options include saline rinses, antihistamines (if allergies are involved), or steroid nasal sprays instead of decongestants.

Can a Sinus Infection Directly Cause High Blood Pressure?

Sinus infections don’t directly cause high blood pressure. However, inflammation, pain, and stress from severe or chronic sinus infections can lead to temporary spikes in your blood pressure.

How Can I Lower My Blood Pressure During a Sinus Infection?

Here are some tips to help manage blood pressure while dealing with sinus issues:

• Try steam inhalation or nasal irrigation (like a neti pot) to relieve congestion.
• Use a humidifier to reduce nasal irritation.
• Choose blood pressure-safe medications—always ask your doctor or pharmacist.
• Prioritize rest and stay hydrated to reduce stress on your body.

When Should You See a Doctor About Sinus-Related Blood Pressure Changes?

Consult an ear, nose, and throat (ENT) specialist for help if you experience:

·       Blood pressure readings consistently higher than usual during or after sinus infections.

·       Symptoms like dizziness, severe headaches, or vision changes.

·       Sinus symptoms lasting more than 10 days, as this may indicate a bacterial infection.
