1) FIRST of all, his Doctor SHOULD BE referring him to a Nutritionist.
THEY will tell you, what foods your Husband can/cannot eat, how to eat, recipes, how to cook, and give you information and answer your questions.
Whatever way you cook for him, it HAS TO BE, per his Diabetic condition.
2) My late Dad was Diabetic. So I know how this is. My Dad also had heart problems/high blood pressure, high cholesterol, and complications from Diabetes. It affects your entire body and circulatory system and nervous system. My Dad also had eye problems because of it. And was on Dialysis 3 times a week. He also had had open-heart surgery.
He died, from Diabetes.
3) Ultimately, your Husband has to be the one to do what is needed. He needs to exercise, and eat properly. A Nutritionist will tel him how. Per HIS condition.
4) As a Wife, you do the best you can. But "nagging" a Husband about it will not help. Diabetes is life altering and very unnerving for many Men.
It can also affect Libido. Know that.
My Mom would nag my Dad and really say to him how frustrating it was that he had these health problems. It does not help. It makes it worse.
Know that.
Ultimately, a Husband needs a partner..... in all of this, and acceptance.
And joining a community 'support group' can also help. For HIM.
5) I took my Dad to all his Doctor appointments. He could no longer drive due to his failing eyesight from Diabetes. I spoke to his Doctors in front of my Dad. To learn myself, what his condition is and what to do... even per his medications.
6) You CANNOT do this for him. You CANNOT do this without knowing, real knowledge about it from a Professional or a Nutritionist. Because- each person's condition, is different. It is NOT a one size shoe fits all.
You can tell your Husband about my late Dad.
There was a point, that my Dad would NOT even tell us or my Mom, about what the Doctor's told him about his condition.
His health deteriorated.
Once you have Diabetes, you cannot cure it.
You have to manage it.
Not by running marathons, but everyday things. Even if that means walking up and down the street. Per HIS level of condition.
My Dad, died because of it. He also had had a Stroke.
Before that happened, my Dad's health deteriorated to the point he could NOT even work anymore. And he had his own business. My Dad was a self-made man and very successful. HE was in construction TOO... and put together HUGE projects and commercial developments. He knew construction, development, project management, and did Consulting for contractors too.
I know about that all.
Help your Husband, but don't nag him. Not saying you do.
Assist him.
Be his "Partner" in this.
A Man... has unique emotions about it. And how their life may or may not change. Due to Diabetes.
Let him vent.
Let him worry too and be there for him.
Let him talk about it.
He cannot just do, what everyone else is doing per his condition. In other words, don't just do what someone else says... because it may not be, appropriate for him.
You need to see a Nutritionist. Per HIS condition and liver issues.
He should also see a specialist.
My Dad, per his condition, REGULARLY saw:
His PCP
His Eye Specialist
His Renal Doctor (kidney doctor)
His Heart Doctor.
A Nutritionist
Bear in mind, that even "skinny" people can have Diabetes. It is not only 'fat' people who have it.
All the best,
Susan
