Dear friend .. Greetings from HCM.. I have read your query and I understand that your sodium level is bit low than the normal reference range.. But you need not worry each lab will have different reference ranges .. Find out the ref range for that particular lab .. And even then its very minimal difference .. Need not worry ... U take salt intake as usual daily you are consuming .. It will be alright .. Take enough intake of fluids .. And do exercise as your triglycerides are very high .. Cut down the carbohydrates and take more of proteins and fiber rich diet like green leafy vegetables, it's, whole grain s and fruits .. You will be alright .. Check your fasting glucose and HbA1c levels too and later you contact us .. Thank you take care
