i'm glad you brought up a urinary tract infection (uti) because that is the first thing that jumped into my mind. it's possible for utis to occur again and again. for that reason alone it would be worth taking your father back to his primary health care provider for an exam. this will also give you an opportunity to discuss your other concerns with a medical professional. not eating can be a sign of some underlying condition that requires treatment (or hospice care depending on your father's wishes). it's not unusual for elderly people to gradually lose their sense of balance or to experience degenerative spinal problems that lead to weakness in the legs arms etc. regardless of the cause of your father's balance problems he may need to consider using an assistive device such as a walker on days when his balance isn't so good. wishing you all the best!
my elderly father will go from walking perfectly one day to not being able to walk the next. what's the problem? . normally my dad is able to walk and do normal things. but it can change in a single day and he is unable to walk and doesn't eat. when this first happened he had a uti. he took antibiotics and was fine within a day. but now it's happening more.
