Hi

Please try to look at what are the stressors in his life, how is it affecting him and what can be done to work around those situations. If he can start any exercise routine each day would be helpful.

Hi, There are many reasons for lack of sleep.It can be due to environmental factors, physical factors,psychological factors.Talk to your father about any changes in these factors.You can consult a clinical psychologist for psychological assessment

Connect with psychiatrist and psychologist

There can be endless reason , these can be  physical or psychological . For physical reason visit doctor and for  psychological reason visit psychologist or psychiatrist. If you are worrying about your father health in that case you can go for counselling.

The urgent need, I feel, is to consult your father's diabetes doctor. There may be a need to assess his blood sugar level and other health parameters to understand more about his symptoms. If he is cleared in terms of physical health after the assessment and modification in the treatment and yet he continues to have the same symptoms of insomnia, do consult a psychologist for assessment of his mental health. He can try to engage himself into any mentally relaxing exercises or hobbies that he can pursue which will make him feel relaxed.

Insomnia can be due to various reasons. Needs to rule out. It can be well treated with counseling sessions and homeopathic medicine if required. You need an expert Psychologist who is a good homeopathic physician.

Maybe he is going through some stress which he is unable to share and discuss with you people.. Suggest you to fix an appointment with a therapist for him sonthat he can open up and vent out his concerns and emotions to get a clarity and solutions.

Suggest to your dad that talking to a doctor about his sleep is a good idea. Doctors are like sleep experts who need to know everything about his day, stress, and recent changes. It's like sharing all the pieces of a puzzle so the doctor can give the best advice. Encourage your dad to tell the doctor everything for a more accurate plan to help him sleep better. It's like teamwork between him and the doctor for personalized advice.
