Thoracic Outlet Syndrome

In thoracic outlet syndrome, hand coldness can be a sign that blood flow to the arm has been reduced due to compression of the subclavian artery. In this case, excessive caffeine, nicotine, and cold foods or environments further constrict peripheral blood vessels, amplifying the symptoms. Although food does not create the compression itself, adding a stimulating constriction to already narrowed blood flow can significantly worsen the perceived symptoms. Smoking damages overall vascular health so it must be reduced, and a diet centered on vegetables and Omega-3s, which have anti-inflammatory effects, is recommended as a supplement. The feeling that symptoms worsen after consuming cold foods is an accurate observation from a Korean medical perspective. In individuals with a constitution where waste and fluids accumulate due to weak digestive function or when exposed to cold and damp external stimuli, cold foods damage the body's warm energy, further slowing circulation and exacerbating congestion in already narrowed pathways. At Dongjedang, we view such individuals as lacking the body's warming energy and having blocked circulation. External treatments utilize acupuncture and thermotherapy—or thermotherapy acupuncture if necessary—to revitalize local circulation. Herbal medicine is used to restore the foundation of circulation through constitution-tailored prescriptions that warm the body from the inside and flush out waste and stagnant blood. Regarding dietary management, meals with a warm nature and warm teas such as ginger tea are helpful, and we recommend reducing the consumption of frozen desserts and cold beverages, at least during the treatment period.
