Q My younger sister age 23 year weight 43 kg. Some day before when she was in a marriage ceremony she suddenly fell down, that time her BP went down below 70, than after that we consult to a physician and he told us that she fell due to weakness and he admitted her and gave infusion of DNS and RL and amino acid supplement and she got well. After few days back same problem came and she fell down for a minute only and stand up within minute but she did not get any prior information like unconsciousness, head rounding, sweating etc. And same thing also happen yesterday for a minute only. Can you suggest me what is the problem behind this. She has normal blood report like Hb 11, platelet count 1.85 etc.
Difficult to pinpoint exact cause without an examination. Some probable cause can be postural hypotension, hypoglycemia, weakness, etc. Regular monitoring of blood pressure, tests for her glucose levels and her BMI may give exact idea.
