Tired, Moody, and Gaining Weight? It Could Be Your Thyroid.

You’re tired. You’re cranky. You’ve gained weight without changing a thing, or you’ve lost it without trying. Your periods are weird, your face looks puffier than usual, and your sex drive’s gone on sabbatical. No, it’s not all in your head, and no, it may not be just “stress”.
It may be your thyroid.
This unassuming, butterfly-shaped gland in your neck controls some of the most vital functions in your body, energy, mood, metabolism, heart rate, digestion, and more. When it goes off-track (either too slow or too fast), your whole system can feel the impact. Here are 12 ways your thyroid might be messing with you, and you might not even know it.
At Cedar Endocrine Clinic, located at Mount Elizabeth Hospital and Mount Alvernia Hospital, we help patients uncover the hidden signs of thyroid imbalance every day. If something doesn’t feel quite right in your body, here are 12 often-overlooked ways your thyroid could be involved.
1. You Can’t Think Straight
Constantly zoning out? Forgetting why you walked into the room? That fuzzy mental haze may have a name: brain fog. It’s a classic sign of an underactive thyroid.
2. Your Emotions Are on a Rollercoaster
Unexplained low moods, irritability, or anxiety might not be “just you”. Hypothyroidism can leave you flat; hyperthyroidism can make you edgy and restless.
3. Your Periods Are All Over the Place
Too heavy, too light, or suddenly MIA? Thyroid hormones help regulate your menstrual cycle, and things can go haywire when they’re out of balance.
4. Fertility Feels Like a Mystery
Struggling to conceive? Thyroid dysfunction can quietly disrupt your reproductive hormones, making it harder to get or stay pregnant.
5. You Look... Puffy
If your face feels swollen or your eyelids are puffed up in the mornings, a sluggish thyroid could be to blame. It's not just bad sleep or too much salt.
6. Your Vision’s Acting Up
Blurred or double vision, especially if it seems to come out of nowhere—can be linked to autoimmune thyroid conditions like Graves’ disease.
7. Your Hands Tingle or Go Numb
Pins and needles in your hands, especially at night? That’s not just awkward sleeping positions. It could be carpal tunnel caused by thyroid-related swelling.
8. Food Doesn’t Taste Right Anymore
If your meals suddenly feel bland or metallic, you’re not imagining it. Hormonal changes can dull your taste buds.
9. You’ve Lost Your Libido
Low sex drive with no obvious reason? Thyroid hormones influence your energy, metabolism, and reproductive hormones,
so when they’re off, desire often is too.
10. Your Hair Is Falling Out
A few extra strands in the shower is one thing. But thinning hair or bald patches? That’s a red flag your thyroid might be involved.
11. Your Blood Pressure’s Gone Rogue
Unexplained high or low readings could be your thyroid pulling strings. Overactive thyroids can spike your pulse; underactive ones can make your blood vessels sluggish.
12. Your Gut Is Revolting
Constipated more often than not? Or sprinting to the toilet after meals? Yep, your thyroid regulates digestion, too.
