Why Am I Retaining Fluid?
The blood pressure readings of 109/56mmHg is marginally under limits of normal range.
Hypotension could be a reason for easy fatiguability. Other possible reasons that could be triggering this are
1. Drug induced - Zoloft is considered as one of the cause. Increase in the dose of Zoloft may have caused worsening.
2. Metabolic cause - Diuretic (water pills) such as Hydrochlorothiazide can lead to reduced sodium levels. 'Hyponatremia' is one of the commonest causes of easy fatiguability.
I suggest you to report back to your primary physician. Physical examination and blood tests to look at the serum sodium level are entailed. Perhaps modifying the doses of your medications and correction of hyponatremia (if found) is suggested.
Hope my answer is both adequate and informative. Should you have any more concerns, I will be available to follow up.
