Low pulse pressure, or low blood pressure, is not always indicative of a health problem and it is usually not alarming to doctors unless the patient is exhibiting other symptoms caused by the low blood pressure, according to the American Heart Association. These symptoms can include dizziness, lightheadedness, fainting, unusual thirst or dehydration, inability to concentrate, blurry vision, nausea, clamminess, cold or pale skin, rapid and shallow breathing, fatigue and depression.
If the patient is exhibiting symptoms associated with low blood pressure, it can be indicative of quite a few health issues that may or may not be serious, as noted by the American Heart Association. Non-serious health conditions that lead to low blood pressure include pregnancy (pregnant women often experienced decreased blood pressure during the first 24 weeks of pregnancy), certain medication use (diuretics and other drugs used to treat hypertension, among other medicines, can lead to low blood pressure) and nutritional deficiencies (a patient who is deficient in vitamin B-12 or folic acid may suffer from anemia, which can lead to low blood pressure).
More serious issues related to low blood pressure include a sudden loss of blood volume from a trauma or injury; heart problems such as bradycardia, which can cause the heart to not pump blood efficiently through the body; anaphylaxis, which is a serious allergic reaction that is a type of shock that can lead to breathing issues and lower blood pressure; or septic shock, which is a severe infection that occurs when bacteria leaves the site of an infection and enters the bloodstream, producing toxins and affecting the blood vessels.
