How can I manage T1D and autoimmune thyroiditis at 19?

Hello,

Welcome to icliniq.com.

I understand your concern.

Before we go into fine-tuning, can I ask what kind of insulin you are using right now?

There are many different types; some work all day in the background, like basal insulins (for example, Glargine), and others act quickly around meals, such as rapid insulins. A few people use regular insulin, which is slower than the modern rapid ones, and some are on premixed preparations like Mixtard (Insulin isophane and human insulin) that combine both. Knowing exactly what you take helps decide whether we adjust the background dose, the meal dose, or both.

We can definitely get your sugars under steadier control with fewer lows. The usual goal is fasting and pre-meal readings in the 80 to 130 mg/dL range, and two to three hours after meals below 180 mg/dL. An HbA1c (glycated hemoglobin) level of around 7% is a realistic and safe first target.

If you are using both basal and mealtime insulin combinations, then they both need adjustment. On a day when you are feeling normal, check your sugar, skip one meal, keep well hydrated, and recheck every two to three hours. If your numbers drift up steadily, the basal is a bit low; if they keep sliding down, it is a touch high. Make small changes only, one or two units at a time, and give each change two or three days before deciding again.

For meals, and if you are using rapid-acting insulin, try matching the dose to what you eat rather than using a fixed number. A rough guide is the 500 rule: divide 500 by your total daily insulin to know how many grams of carbohydrate one unit will cover. For example, if your total is 50 units a day, one unit covers about 10 grams (0.35 ounces) of carbohydrates.

If you find your sugars climbing two to three hours after eating, you likely need a little more; if you are going low, a little less. When your sugar is above 120 to 140 before meals, it helps to take your rapid insulin 10 to 20 minutes before the first bite, instead of right at the table, so that it is already working when the food starts raising your sugar.

If you ever go low (under 70), treat it promptly, drink half a glass of juice, or take a spoonful of sugar water. Wait 15 minutes, check again, and repeat if it is still low. You may keep a glucagon rescue kit at home, either the nasal spray or the auto-injector, and teach a family member how to use it in case you are unable to treat yourself.

If your sugars are high, you can safely correct them by using the “1800 rule”: divide 1800 by your total daily insulin to estimate how much one unit lowers your sugar. For example, if you take 50 units daily, one unit brings sugar down by roughly 35 mg/dL. Recheck after two to three hours before giving more insulin.

As far as diet is concerned, focus on whole, minimally processed foods, measured portions of whole-grain bread or pasta, brown rice, oats, quinoa, beans or lentils, lean proteins like fish, chicken, or eggs, plenty of non-starchy vegetables, a handful of nuts, and whole fruit instead of juice. Avoid pizza, burgers, and creamy pastas. Newer devices, such as continuous glucose monitors and insulin pumps, help you monitor sugar patterns. These pumps automatically inject the required dose, reducing the chances of both highs and lows.

Please keep up with routine screenings, a yearly eye check, a kidney function test, and a general physical examination. Check your blood pressure and cholesterol, too. Keep flu and pneumonia vaccines updated. About your thyroid, with mild autoimmune thyroiditis and a TSH (thyroid-stimulating hormone) of 4.1, repeat TSH and free T4 (free thyroxine) in about two months.

Do not underestimate sleep and stress; poor sleep or chronic stress hormones can push sugars up and blunt the insulin effect. Aim for seven to nine hours of good sleep, and try a brief daily relaxation habit such as deep breathing, walking, or any activity you enjoy.

I hope this helps you.

Thank you.
