<bot>: Hello, Brief Answer: In young adults, it is normal to have readings like that as long as no symptoms or complaints from the patient. Explanation: My opinion is that the new guidelines in 2017 recommended new ranges of blood pressure readings for the diagnosis of hypertension and prehypertension patients. Readings below 120 systolic and 80 diastolic is considered normal. Some patients may have readings as low as 90/60 and no symptoms or signs of low cardiac output in these patients. I suggest my patients the following follow up your blood pressure regularly. The information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition, I would ask them if your son has any symptoms or signs of low cardiac output. Also, if other comorbidities present. Conclusion: I suggest nothing to be worried about as long as your son is healthy and active. Hope I have answered your query. Let me know if I can assist you further.
