Poor venous return throughout the body is usually related to compression, or venous thrombosis, cardiac insufficiency, and requires general treatment, medication, or surgery depending on the cause. 1. Compression: When the veins are compressed for a long period of time, it is easy to cause poor venous return if the veins are not accessible. It is recommended to apply warm compresses to accelerate blood circulation, and surgery can be considered to relieve the compression if the effect is not good. 2. Venous thrombosis: If there is venous thrombosis, it will easily lead to obstruction of venous return. After diagnosis, anticoagulant treatment should be taken, such as oral warfarin, aspirin, etc. 3. Cardiac insufficiency: If there is heart failure, cardiac insufficiency, etc., it may affect the venous blood flow and lead to obstruction of blood flow. Anti heart failure treatment such as cardiotonic drugs may be given as appropriate, e.g. deacetyl furfuracein, digoxin, etc., which have a positive inotropic effect. If you find that you have poor venous blood flow throughout the body, you need to consult a doctor as soon as possible and analyze the cause of the disease under the guidance of a professional physician before proceeding with the treatment, so as not to delay the condition and cause complications.
