Varicose veins in the arms indicate that oxygen depleted blood is staying in the veins and is not being recycled by circulation. Varicose veins in the arms may occur on the inside of fat and flabby upper arms as well as the insides of relatively skinny upper arms. The contributing factor is therefore not obesity so much as a lack of arm movement.
Some prescription strength heart medications (blood thinners) have been used to treat varicose veins. This was the case of my father who had rather large swollen varicose veins in the legs. Dr. Hsiung of the Shanghai Clinic and Pharmacy on Hengyang Road in Taipei during the 1950s to 1970s prescribed the medication for my father’s varicose veins. At 86 years old, my father walked up four flights of stairs to see Dr. Hsiung. Once my father asked Dr. Hsiung how was his health, and Dr. Hsiung said in return: “You just walked up four flights of stairs, did you not?”
Another contributing factor may be weak circulation of the upper body. If this is the case, shallow pulse, shallow breathing, slight dizziness, may occur if there is varicose veins in the inside upper arms. Obesity in this case would be a major factor.
