The red dots all over the neck may be caused by local capillary rupture and bleeding, and it is recommended to consult a doctor in time. When you are constipated, the red dots all over your neck are mainly considered to be the pressure of the blood vessels in the neck, leading to the rupture of some of the more fragile capillaries, resulting in the formation of hemorrhage, which ultimately led to the occurrence of the symptom. It’s a normal physiological manifestation, and there is no need to worry too much if there are no special symptoms. However, if it occurs repeatedly, you need to consult a doctor in time for coagulation function, local vascular ultrasound and other examinations to clarify whether there is any coagulation function abnormality. If there is a need for targeted treatment, if not, you need to strengthen the exercise, improve the diet structure, so as to alleviate constipation, and change the habit of straining to defecate, which may cause cerebral hemorrhage and other dangerous situations.
