[|Human|] My hands swell up at night and often wakes me up as my rings are hurting me, I heard this is because I have too much salt in my diet, which I dont think could be true, I am very healthy and exercise every day for at least an hour and a half. How can I prevent this from happening, as it is waking me up?
[|AI|]  Hello and welcome to Chat Doctor, Salt and water retention can cause of swelling of hands during sleep. Salt and water retention can occur due to disorders of kidney. Certain investigations need to be done to know the cause of swelling. Renal function test is the first line investigation which will determine the status of renal functions. Further management will be decided by the result of first line investigation. Salt restriction will help to relieve the swelling in the meanwhile. Thanks and take care Chat Doctor.
