My Auntie’s Silent Struggle with Undiagnosed Hypothyroidism

Don’t know, why! But, when I talk about the undiagnosed hypothyroidism symptoms in women, my auntie’s journey always comes to my mind. She was the kind of woman in my life who had radiated warmth in her— the one who cooked me the most nourishing meals with her hands, remembered every birthday of me, and she always held the laugh with her.

Slowly something started to change in her. It was a small change. At first, it was just a fatigue she felt. She usually told us, “Now, I just don’t feel like myself anymore,” and brushing it off as the natural toll of her motherhood and her household responsibilities. Then weight gain came in her. No matter how carefully she ate or how many longs walks she took, the pounds continue to clung stubbornly.

She tried every diet trend she saw in her Instagram feed, every “miracle” tea she listened about, every viral fitness routine, but nothing worked for her. Her friends whispered that maybe “She was just getting older”. But I could see and feel the frustration in her eyes. Doctors told her it was “normal”, that she should “accept it as part of being a woman.”

The truth was hidden in her thyroid that was underactive. These undiagnosed hypothyroidism symptoms in women don’t shout; they whisper. They leave women like my auntie to just suffer her in silence. Her story is not unique. It’s the story of women who are told to “try harder,” “eat less,” or “exercise more”.

Your thyroid plays a role in how your body feels every day.

Why Hypothyroidism Symptoms Go Undiagnosed

You wake up every morning feeling tired because you did not sleep well. You struggle through the day. You think it is because you are stressed.. you have kids to take care of or you are just getting older.

Your jeans are tighter even though you eat the food. Your skin looks dull your hair does not shine like it used to. You feel sad for no reason. These are not movie-like symptoms. They are small your thyroid gland gives you hints every day.

Weight Gain That Defies Diets

Slowed Metabolism

When your thyroid hormones drop, your body burns less calories at rest. 1 Even your small meals can feel like they “stick” to your body. My auntie once said to me, “I eat less than everyone else at the table, but I’m the only one gaining weight.” That’s the cruel trick of weight gain in hypothyroidism you can never underestimate — it makes women feel guilty for themselves.

Fluid Retention

Hypothyroidism can cause mild swelling in you, adding extra pounds to you that aren’t fat but just your water weight. 2

Fatigue & Low Activity

Constant tiredness makes exercising really tough. This reduces how calorie you burn and also affects your muscle tone.

Hormonal Imbalance

Thyroid dysfunction mess up your estrogen and progesterone levels. This can make it harder to lose weight when you’re pregnant having fertility issues or going to menopause.

  • Selenium is also very important. We can get it from Brazil nuts and eggs and sunflower seeds because selenium helps to regulate our thyroid enzymes. Selenium is really good for our thyroid enzymes.
  • If we want to focus on protein we should eat meats and legumes and dairy because protein helps to stabilize our metabolism. Protein is very important for our metabolism.
