Introduction

High blood pressure itself does not directly cause eye swelling, but poor long-term control or the development of complications may indirectly lead to swelling around the eyes. It is essential to strictly manage blood pressure through a low-salt diet, regular作息 (daily routine), and avoiding staying up late or excessive fatigue. If eye swelling occurs, it is important to investigate potential kidney issues or local eye conditions, while also strengthening blood pressure monitoring and management to reduce the risk of swelling caused by complications.

Generally, high blood pressure itself does not directly cause eye swelling. However, when blood pressure remains poorly controlled over a long period or complications arise, it may indirectly lead to swelling around the eyes. The detailed explanation is as follows:

When elevated blood pressure has not yet affected organ function, it does not directly result in eye swelling. Periorbital edema is more commonly related to local factors such as lack of sleep, allergies, or ocular inflammation. In these cases, if blood pressure is maintained within the normal range, the swelling typically resolves once the triggering factors are removed.

Long-term hypertension may damage kidney function, leading to disturbances in sodium and water metabolism and fluid retention in the body, which can result in eyelid edema. At the same time, it may cause retinal vascular changes, worsening congestion in ocular tissues and making swelling more apparent. This is often accompanied by persistently high blood pressure, dizziness, and other symptoms.

In daily life, it is essential to strictly control blood pressure by adhering to a low-salt diet and maintaining regular作息 (daily routines), avoiding late nights and excessive fatigue. If eye swelling occurs, it's important to evaluate potential kidney issues or local eye conditions, while also strengthening blood pressure monitoring and management to reduce the risk of swelling caused by complications.

What are the benefits of saffron for high blood pressure?

Saffron offers benefits for hypertension, including assisting in blood pressure regulation, improving vascular elasticity, alleviating anxiety, promoting blood circulation, and helping regulate blood lipids. However, these effects should only be considered as complementary to standard antihypertensive treatments and cannot replace prescribed medications. If blood pressure fluctuations or any discomfort occur after consuming saffron, medical advice should be sought promptly. The active components in saffron can mildly dilate peripheral blood vessels.

Can anxiety disorder cause high blood pressure?

In general, whether anxiety disorder leads to elevated blood pressure depends on the specific circumstances. When anxiety attacks are mild and short-lived, they usually do not cause an increase in blood pressure. However, if anxiety attacks are frequent and severe, they may lead to elevated blood pressure and require attention and management. To prevent anxiety disorder from affecting blood pressure, it is important to manage emotions effectively in daily life.

Can anxiety cause high blood pressure?

Anxiety disorders may lead to elevated blood pressure. During an anxiety episode, the body's stress response is activated, stimulating the sympathetic nervous system and increasing hormone secretion, which in turn causes blood vessel constriction and a faster heart rate, ultimately resulting in a temporary rise in blood pressure. This phenomenon is relatively common among individuals with anxiety disorders. If blood pressure frequently increases or is accompanied by symptoms such as chest tightness or dizziness, prompt medical attention is recommended.

In general, whether glaucoma is related to hypertension depends on the specific circumstances. When hypertension is well controlled, it usually has no direct association with glaucoma. However, if hypertension remains uncontrolled over a long period, it may increase the risk of developing glaucoma or worsen its progression, which requires attention. To reduce the risk of interaction between the two conditions, strict blood pressure control in daily life is essential.
