<s>[INST] Hi, my wife has been experiencing sudden weakness on her right arm and right leg. This had happened 4 times during the last two years. Every time she would just all of a sudden feel dizzy and just faint. She would then wake up about half an hour or so later. What s wrong with her? [/INST] Hello, As in females, it's become off late common to faint and lead to tension in the home. But this is totally related to lower hemoglobin and low iron levels. Having a blood routine to check the HE will be good as an oral supplement of iron and calcium medicines or through diet can be helpful. Indulging into physical activity will be on a positive note. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.  </s>
