How microplastics affect Hashimoto’s

Microplastics are small pieces of plastic that are under five millimeters in size. They’re omnipresent in the environment and have many effects on your health (1–6).

Microplastics have been found in the ocean, drinking water, fresh water, food, and air (7–15). Certain plastics contain components that are harmful to your health, most notably BPA (Bisphenol A) and phthalates (16–18). They’re considered endocrine disrupting chemicals (EDCs) — meaning they interfere with how your endocrine system operates (19–21).

Microplastics can enter your body through your:

  1. Digestive system
  2. Lungs
  3. Skin

Once microplastics are in your body, they enter your bloodstream and trigger inflammation (8, 22, 23). Problems that can occur include difficulty breathing, autoimmune reactions, changes in hormone production, and alterations in certain proteins (19).

BPA and phthalates can disrupt thyroid function (24–26):

  • Reducing T4 and T3 hormone levels
  • Increasing TSH levels
  • Reducing the uptake of iodine from the thyroid

As microplastics can trigger autoimmune reactions, they might be responsible for triggering Hashimoto’s flare-ups (19, 27).

Protect your thyroid health, as well as the health of others and the environment with five things you can do to reduce the spread of microplastics:

  1. Stop using single-use plastics (or cut down your use — this includes plastic cutlery, straws, plates, cups, and bottles)
  2. Use a reusable bag while shopping
  3. Use a reusable bottle or mug for your beverages (even when ordering to-go from cafes)
  4. Check your beauty routine (avoid scrubs and soaps that contain microbeads)
  5. Use a razor with replaceable blades instead of disposables
