Struggling with constipation? 💩 Increasing dietary fiber can help—but the key is to do it slowly. Most Americans consume about 5g of fiber per day, but the recommended intake is 20–30g per day for healthy digestion.

Jumping straight to 30g can lead to bloating, gas, and even worse constipation at first. Instead, gradually increase your intake:
➡️ Start around 10g/day
➡️ After a few weeks, increase to 15g/day
➡️ Slowly work up to 20–30g/day

And yes—prunes can help constipation! They’re high in fiber (about 10g per prune), which supports regular bowel movements. Just remember that they also contain natural sugars, so moderation matters.

Constipation Part 1: The Hydration Fix! 💧

Struggling with constipation? Start with this simple solution! 🍀

The FIRST step to relief: proper hydration. Drink 1.5-2 liters of total fluids daily (not just water!) to help things move naturally.

Yes, prunes work too! 🌟 But lifestyle & dietary changes are your best first line of defense.

Stay tuned for Part 2! ➡️

Prolia can significantly improve bone mineral density in people with osteoporosis. 📈 In men, studies show lumbar spine BMD can increase ~5.7% in 1 year and up to 8% in 2 years, while the hip improves ~2.4–3.4%. In postmenopausal women, spine BMD may rise 9.2% in 3 years and up to 21.7% over 10 years, with hip gains up to 9.2%.

But here’s the key: stopping Prolia without another osteoporosis medication can reverse those gains within 18–24 months and increase vertebral fracture risk. Always have a treatment plan before discontinuing.

“Why don’t endocrinologists check all thyroid hormones?”

Just because we can measure a hormone doesn’t mean it’s clinically useful.

For example, some people ask about T2. It’s a minor thyroid hormone metabolite that exists only in trace amounts and currently has limited evidence of meaningful physiological impact in humans. Because of that, it’s not routinely measured.

The labs that actually help diagnose and manage hypothyroidism are:
• TSH
• Free T4
• Sometimes Free T3

Endocrinologists spend years in specialized training learning which labs are truly helpful for diagnosis and treatment.

More tests don’t always mean better care—the right tests do.

Did you know body composition can affect your levothyroxine dose?

People with obesity often require higher doses of levothyroxine. This is because thyroid medication distributes differently in the body and may clear at a different rate.

That’s why many experts recommend calculating thyroid medication based on lean body mass—not just total body weight.

If your thyroid levels or symptoms aren’t improving, your dosing strategy may need adjustment.

Up next in the final part: Why testing every hormone isn’t always helpful.

Still not feeling better on levothyroxine after radioactive iodine treatment? Your gut and medication timing could be the reason.

Certain factors can block or reduce absorption of thyroid medication:
• Bariatric surgery can cause medication to move through the GI tract too quickly
• PPIs (like omeprazole/Prilosec) can interfere with absorption
• Calcium and iron supplements can block levothyroxine from being absorbed

If you take calcium, iron, or PPIs, you should separate them from levothyroxine by at least 4 hours.

And remember:
✔ Take levothyroxine on an empty stomach
✔ Wait at least 30 minutes before eating

Yes, the timing can get tricky—but working with your provider can help you find a routine that works for your body.

Hypothyroidism after radioactive iodine treatment is common—but manageable.

“Permanent” doesn’t mean your symptoms can’t improve or that you’ll feel sick forever. Many people do very well on treatment.

However, about 10–15% of patients don’t feel fully back to baseline on levothyroxine alone. There are a few reasons why:
• Some people don’t convert T4 to T3 efficiently and may benefit from adding Cytomel
• Rare cases of thyroid hormone resistance may require different dosing
• Gut issues like celiac disease or malabsorption can prevent the medication from being absorbed

Sometimes patients take their medication perfectly… but their body simply isn’t absorbing it.

The key: If you still don’t feel well, there may be a reason—and solutions.

Part 2: After Radioactive iodine therapy, most patients do great on Levothyroxine (T4) — about 80–85% feel back to normal once TSH is optimized. 🙌

But 15–20% still have symptoms. That’s when we may add T3 like Liothyronine (Cytomel) for a more personalized approach.

FDA-approved T4/T3 is preferred over desiccated thyroid (like Armour Thyroid) to better match human thyroid ratios.

03/05/2026

After Radioactive iodine therapy (I-131), the goal is to treat hyperthyroidism — but 99.9% of the time it results in permanent hypothyroidism.

That means you’ll likely need lifelong Levothyroxine to replace thyroid hormone.

It’s not a failure — it’s expected. Proper thyroid hormone replacement = feeling like yourself again. 💊✨

FINAL PART – Multinodular Goiter 👇

When evaluating a multinodular goiter, we biopsy the most suspicious nodule — not the largest.

On ultrasound, these features raise concern:
▪️ Hypoechogenicity (darker than surrounding thyroid tissue)
▪️ Irregular or jagged margins
▪️ Microcalcifications
▪️ Taller-than-wide shape
▪️ Extrathyroidal extension or abnormal lymph nodes
▪️ Solid composition (fluid-filled is usually lower risk)
▪️ Spongiform but solid appearance with punctate changes

These characteristics determine whether a nodule has 2, 3, 4, or 5+ suspicious features, which guides biopsy decisions.

It’s not about size alone.
It’s about the ultrasonography risk pattern.

PART 5 – When do tiny nodules get biopsied? 👇

If a thyroid nodule has 5 suspicious ultrasound features, biopsy is considered even if it’s 5–10 mm (0.5–1 cm) — especially with strong risk factors.

In someone with:
▪️ Personal history of breast cancer
▪️ Family history of thyroid cancer

➡️ 4+ suspicious features = strong consideration for biopsy.

Growth also matters
✔️ 20% increase in two dimensions
✔️ OR 50% increase in volume (often checked year to year)

This is exactly what your endocrinologist and radiologist evaluate on your annual ultrasound.

A tiny nodule doesn’t always mean a tiny risk.

PART 4 – Imaging 👇

The foundation of thyroid nodule evaluation?
✔️ High-resolution thyroid ultrasound with TIRADS

TIRADS looks at:
▪️ Size
▪️ Solid vs cystic
▪️ Echogenicity (hypo, iso, hyper)
▪️ Margins (smooth or irregular)
▪️ Calcifications
▪️ Vascularity
▪️ Lymph nodes

Not all nodules need biopsy — ultrasound risk stratification guides us.
