In this episode of the Diabetes Podcast, Richie and Amber unpack Alpha Cell Dysfunction—the last stop in DeFronzo’s “ominous octet.” We explain why your blood sugar can rise overnight, what alpha cells do in a healthy body, how things go wrong in type 2 diabetes, and what you can do—today—to take back control. We also cover meds that target this defect and the simple “non‑prescription prescription” of food and movement.

If you’ve wondered why fasting blood sugar is high even when you skip a snack, this one is for you.

• What alpha cells do and how glucagon works with insulin
• What goes wrong in Alpha Cell Dysfunction (glucagon “gone rogue”)
• Why fasting and after‑meal sugars run high
• Where it fits on the timeline from insulin resistance to type 2 diabetes
• Meds that can help: GLP‑1s, SGLT‑2s, and DPP‑4s (who, how, and cautions)
• Food moves: fiber-rich carbs, intact grains, pairing, and what to limit
• Movement that helps your liver and hormones: walking, aerobic, and strength
• Simple action steps to start today

• 00:00 Welcome + why Alpha Cell Dysfunction matters
• 01:20 What alpha cells do in a healthy body
• 03:30 What goes wrong in type 2 diabetes
• 06:00 When Alpha Cell Dysfunction shows up in the timeline
• 10:45 Medications that can help
• 14:00 Food strategies that support balance
• 18:00 Movement that fixes the signal
• 22:00 The “non‑prescription prescription”
• 23:30 Closing and next steps

• Alpha cells live in your pancreas.
• They make a hormone called glucagon.
• Glucagon tells your liver to release stored sugar (glycogen).
• This helps during fasting, exercise, and when blood sugar drops.
• Insulin and glucose normally “turn down” glucagon after a meal.
• Think of a seesaw: insulin on one side, glucagon on the other. That balance keeps your blood sugar steady.

With Alpha Cell Dysfunction, the alpha cells stop listening. They become resistant to the normal “slow down” signal from insulin and glucose. So:

• After you eat, insulin rises…but glucagon does not fall like it should.
• The liver keeps making and releasing sugar even when blood sugar is already high.
• Fasting sugars rise. After‑meal sugars rise too.

It feels like your pancreas is pressing the gas and the brake at the same time. Your liver gets mixed messages and keeps dumping sugar. Not helpful!

It starts before diagnosis. Here’s the simple flow:

1. Insulin resistance shows up first (muscle, liver, fat). Blood sugar may still be normal.
2. The pancreas makes more insulin to keep sugars in range (compensation).
3. Impaired glucose tolerance: after‑meal sugars start to spike. Early alpha cell issues can show here (glucagon not suppressed well after meals).
4. Impaired fasting glucose: fasting sugars rise. Alpha Cell Dysfunction is now clear.
5. Type 2 diabetes: fasting ≥126 mg/dL or random ≥200 mg/dL with symptoms.

Nerve damage and other changes can start years before diagnosis. So if you have prediabetes or type 2 diabetes, it’s safe to say your liver may be “not helping” and Alpha Cell Dysfunction is likely part of the picture.

Talk to your clinician to see what is right for you. Here’s what we covered:

GLP‑1 receptor agonists

• Examples: Ozempic, Trulicity; higher‑dose versions for weight loss include Wegovy.
• Also: Mounjaro and Zepbound (work on similar hormone pathways).
• How they help: they lower glucagon when sugars are high, in a glucose‑dependent way. They do not block glucagon when sugars are low.
• Common side effects: nausea, vomiting, diarrhea.
• Do not use if you or your family have a history of medullary thyroid C‑cell tumors.

SGLT‑2 inhibitors

• May help overall control. Evidence on glucagon effects is mixed. Still can be useful for many people for other benefits.

DPP‑4 inhibitors (for example, Januvia)

• Help preserve your own GLP‑1 activity so glucagon drops after meals.
• Often work better in earlier stages.
• Do not combine a DPP‑4 with a GLP‑1 since they act on the same pathway.

Meds can help. But lifestyle still moves the needle the most and fixes many defects at once.

Focus on simple changes you can keep doing.

• Eat fiber‑rich, minimally processed carbs
  • Beans, lentils, peas
  • Non‑starchy veggies (broccoli, cauliflower, peppers, greens, mushrooms, onions if you like them)
• Choose intact whole grains
  • Look for “whole wheat flour” or “whole grain” as the first ingredient.
  • Oats count. Steel‑cut or slow‑cooking oats are best.
• Pair your carbs with protein and healthy fats
  • This slows digestion and smooths your sugar curve.
• Limit refined grains and added sugars
  • White flour and sugary drinks can spike you fast and worsen the insulin‑glucagon mismatch.
• Cooked vs raw
  • Cooking is not “bad processing.” Some veggies give more nutrition when cooked.
  • The best way is the way you will eat. Just eat the dang broccoli.

Movement makes your liver more sensitive to insulin. It also improves hormone signals that involve glucagon.

• Walk after meals
  • Even 2 minutes helps blunt a spike. More is better if you can.
• Aerobic activity
  • Moderate to intense sessions improve liver insulin sensitivity.
  • Build up slowly. If you have been inactive, do not jump into hard intervals.
  • HIIT or sprint intervals can help later, once you have a base. Avoid injury.
• Resistance training
  • Start with body weight. Add load over time.
  • Helps lower fasting glucose and improves overall control.
• Keep moving
  • Too much rest after a small tweak can make things worse. Gentle, smart movement helps you heal.

These same habits help insulin resistance, protect beta cells, and support Alpha Cell Dysfunction—all at the same time.

• After your next meal, walk for 2–10 minutes.
• Add one serving of beans or lentils today.
• Swap white bread for true whole‑grain bread (check the first ingredient).
• Pair carbs with protein and healthy fat at each meal.
• Do two short strength sets (bodyweight squats, wall push‑ups) 2–3 times this week.
• If you and your doctor choose meds, learn how they affect glucagon and fasting sugar.
• Build up your activity slowly. Aim to be consistent, not perfect.

• “It’s like pressing the gas and the brake at the same time.”
• “Simple, not easy. It doesn’t have to be complex to work—but it does have to be consistent.”
• “People have more power to change this than they think.”
