Hello: (1) Long-term smoking is one of the main culprits of cardiovascular diseases, as it can damage endothelial cells in blood vessels over time, potentially leading to damage in the lower limb venous system and resulting in lower limb edema.
However, there are many factors that can cause lower limb edema, and it requires evaluation by a cardiologist to determine the cause.
(2) More than 90% of patients with hypertension have primary hypertension, which is related to factors such as constitution, genetics, and dietary lifestyle habits.
The assessment of lower limb edema should also be determined after evaluation by a specialist.
Sincerely, Dr.
Lin Chi-Hsiung, Taoyuan Hospital, Department of Health, Executive Yuan.

More Info

Hypertension, commonly known as high blood pressure, is a significant health concern that can lead to various complications if left untreated. It is essential to understand the underlying causes and the potential relationship between hypertension and symptoms like leg edema (swelling).
1. Impact of Smoking on Hypertension and Leg Edema:
Smoking is a well-established risk factor for hypertension. The chemicals in tobacco can damage blood vessels, leading to increased arterial stiffness and elevated blood pressure. Additionally, smoking can contribute to the development of atherosclerosis, a condition where arteries become narrowed and hardened due to plaque buildup. This can further exacerbate hypertension and lead to complications such as heart disease and stroke.

Regarding leg edema, smoking can indirectly contribute to this condition. While smoking itself may not directly cause leg swelling, it can lead to cardiovascular issues that may result in poor circulation. When blood flow is compromised, it can lead to fluid retention in the lower extremities, causing edema. Furthermore, smoking can affect kidney function over time, and impaired kidney function can also lead to fluid retention and swelling.

2. Recommended Tests for Hypertension and Leg Edema:
If you are experiencing high blood pressure and leg edema, several tests can help identify the underlying causes and assess your overall cardiovascular health:
- Blood Pressure Monitoring: Regular monitoring of blood pressure is crucial. It can be done at home or during visits to a healthcare provider. This helps in understanding the patterns and severity of hypertension.

- Blood Tests: A complete blood count (CBC), basic metabolic panel (BMP), and lipid profile can provide insights into kidney function, electrolyte balance, and cholesterol levels. Elevated creatinine levels may indicate kidney impairment, which can contribute to edema.

- Urinalysis: This test can help detect protein in the urine, which may indicate kidney damage or disease. It can also reveal signs of infection or other urinary tract issues.

- Echocardiogram: An ultrasound of the heart can assess heart function and structure. It can help identify any heart-related issues that may be contributing to hypertension or edema.

- Doppler Ultrasound: This test evaluates blood flow in the veins and arteries of the legs. It can help identify any blockages or venous insufficiency, which can lead to leg swelling.

- Electrocardiogram (ECG): An ECG can help detect any irregularities in heart rhythm or signs of strain on the heart, which can be associated with hypertension.

- Chest X-ray: This imaging test can help assess the size and shape of the heart and check for fluid in the lungs, which can be a sign of heart failure.

In conclusion, smoking is a significant risk factor for hypertension and can contribute to leg edema through various mechanisms. If you are experiencing these symptoms, it is crucial to consult with a healthcare provider who can recommend appropriate tests and develop a management plan tailored to your needs. Lifestyle modifications, including smoking cessation, dietary changes, and regular exercise, can significantly improve your overall health and help manage both hypertension and edema effectively.
