Hi,My name is Jon. You can consider me as a health freak since the start of this year. The reason being is that I just had an episode of high cholesterol, including stressful situations in office, therefore experiencing heart palpitation, nausea, sweaty hands and hard of breathing.Thank God, I had a change of mindset (coz i dont wanna die) and had to eat proper foods (mainly vegetables, fish, no dairy products,and lots of fruits) and exercise. After 3 months, things got back to normal, except the feeling of anxiety. I thought then its an blood ph imbalance, so i ate more fruits, but to no avail. Ive had my insides/abdomens checked (ultrasound),all are normal, had my liver and kidneys checked, results are normal,had my triglycerides and cholesterol checked, normal,except for LDL (.5 units lower than the lowest in range, i think its caused by lots of jogging). There was this time wherein i physically felt as if the anxiety just turned off without any reason at all, and it lasted for 2.5 weeks, then it turned on again. I hate this feeling. It feels like there s an impending doom, therefore causing me to have sleepless nights. I dont know what kind of doctor do i have to go to, hematologist? endoctrinologist? nutritionist? can you please guide me on this?Jon

Hello! Welcome and thank you for asking on Chat Doctor! I passed carefully through your question and would explain that your symptoms seem to be related to anxiety. Low cholesterol levels can contribute in sleep disturbances and in anxiety too. Coming to this point, I would recommend consulting with a specialist of this field (psychotherapist or psychiatrist), who can help you to deal with your anxiety professionally. Yoga and meditation can help too. I would also encourage you to continue on your healthy diet and your daily physical activity. Hope you will find this answer helpful! Kind regards,
