Poor digestion does not directly cause low blood pressure, but there is a correlation with lower blood pressure, mainly due to nutritional deviations. Poor digestion and absorption will affect the function of the gastrointestinal tract, affecting the absorption of nutrients, but will not directly lead to lower blood pressure. If poor digestion goes unchecked for a long time, it may lead to malnutrition, which may further lead to abnormal blood circulation conditions and cause lower blood pressure. Thus, overall poor digestion can have an effect on low blood pressure, but is not a direct factor. If there is obvious poor digestion, accompanied by a decline in physical condition, you need to consult a doctor in time for observation, further examination of the physical condition, and standardized treatment under the guidance of the clinician after diagnosis of the condition, to avoid delays in the condition.
