10 Early Signs Of Thyroid Disease

Despite its critical importance, many people don’t even know where their thyroid gland is located or what exactly it does. Wonder no more. The thyroid is a small gland shaped like a butterfly that drapes over the front of your windpipe. It releases two hormones, nicknamed T3 and T4, which direct how your cells use energy. The thyroid also regulates growth and metabolism.

Disorders of the thyroid are very common, with about 12% of people worldwide experiencing a problem at some point. Unfortunately for females, women are about eight times more likely to have thyroid issues than men. But the risk increases with age for everyone.

Thyroid disease happens when the levels of hormone are too high or too low for proper function. When levels are too low, it is called hypothyroidism, levels too high indicate hyperthyroidism. It is important to nip either one of these conditions in the bud. They are quite treatable, but left unchecked, can lead to infertility, heart disease, and kidney disease.

Because one condition involves too much thyroid hormone and one involves too little, the symptoms of each are like two sides of a coin. Following are 8 pairs of symptoms to watch out for and 2 that are actually the same for both conditions. You’ll be fascinated by these last two, which cause the same symptom in very different ways.

1. Feeling Tired vs. Feeling Jittery
The hormone released by the thyroid controls energy levels and signals cells when it is time to wake up or to sleep. The most common symptom of hypothyroidism is feeling tired and worn out, no matter how much you rest, because you don’t have enough hormone to properly signal cells. You may also experience low motivation and mental exhaustion on top of physical sluggishness.

On the flip side, people with too much thyroid hormone feel nervous and jittery. You may not be able to stay seated or to focus on any one task. That’s because your cells are flooded with the message to go-go-go. This can also manifest in anxiety, tremors, or difficulty sleeping.

2. Gaining Weight vs. Losing Weight
When your thyroid hormone levels are low, you are likely to move less due to exhaustion. On top of that, your metabolism switches tracks. Rather than burning calories for energy and growth, the amount of energy used at rest decreases and your body begins to store more calories as fat. Even if you don’t eat more calories, people with newly diagnosed hypothyroidism gain an average of 15-30 pounds in the first year!

Too much thyroid hormone has the opposite effect. You are more likely to be moving a lot and your metabolism speeds up. As a result, you may lose weight despite having a bigger appetite. However, don’t rely on weight loss as confirmation of hyperthyroidism. Eating more can increase your weight even with an overactive thyroid.

3. Feeling Cold vs. Feeling Hot
When your body burns calories, heat is the byproduct. When you have hypothyroidism, your basal metabolic rate goes down and you produce less heat.

Approximately 40% of people with low thyroid hormone report that they feel colder than others in the same room. This is an important symptom to note if it has come on suddenly – if you are always colder than everyone else, it could simply be your norm.

It stands to reason, then, that people with too much thyroid hormone feel hotter than usual. A ramped-up metabolism and high rate of calorie burn produces a lot of heat. Additionally, thyroid hormone bumps up the thermostat on a type of specialized fat called brown fat, which generates heat and is meant to assist survival in cold climates.

4. Dry, Itchy Skin vs. Swollen, Moist Skin
Skin changes can be caused by a lot of things, so don’t jump right to thyroid disorder if you experience this symptom. However, having either too much or too little thyroid hormone can definitely affect the texture and quality of your skin.

Much like hair follicles, skin cells typically have a high turnover.  When that turnover slows due to hypothyroidism, cells hang around longer before being shed and replaced. That leads to dry and irritable skin. But when the cells are turning over too quickly, you’ll find your skin thickens and appears swollen and moist.

5. Depression vs. Anxiety
Depression and anxiety often go together, but they are different things. People can have both, but depression is more often linked with fatigue and low mood, while anxiety is a restless feeling of discord that makes it hard to calm down. Depressed people may struggle to get out of bed while people with anxiety may have trouble going to bed at all.

Hypothyroidism is commonly linked with depression because of its connection with low energy, while anxiety is a frequent side effect of hyperthyroidism. But because depression and anxiety represent opposite ends of the same pendulum, you can’t necessarily rely on having either one as a proof of a thyroid disorder.

6. Trouble Concentrating vs. Trouble Remembering
Both hypothyroidism and hyperthyroidism can have negative effects on cognition. When your thyroid hormone is too low, you may experience memory problems, especially verbal memory. Untreated, hypothyroidism can actually shrink the volume of your hippocampus.

Hyperthyroidism can also cause cognitive impairment. In this case, patients suffer poor concentration, slowed reaction times, and decreased spatial organization and visual processing abilities.

7. Constipation vs. Diarrhea
Hypothyroidism impacts the health of your digestive system in a couple of ways. First, it slows metabolism and the action of the entire digestive tract. Second, it weakens the muscles that contract the colon and move stool along. The result is painful constipation.

Though hyperthyroidism also comes with muscle weakness, it typically speeds up your system and rushes food through the digestive tract. That tends to result in loose stools and wasted nutrition. Chronic diarrhea may also contribute to the weight loss common with hyperthyroidism.

8. Heavy Periods vs. Irregular Periods
Both overactive and underactive thyroid function can affect menstruation. With hypothyroidism, or low thyroid function, you may experience either heavy or irregular periods.

Your flow could be extremely heavy one month and missing the next. On the other hand, missed or unpredictable periods are more often associated with hyperthyroidism. Both conditions carry an increased risk of miscarriage and birth defects.

9. Muscle and Joint Weakness
When you have low thyroid levels, your metabolic switch flips toward catabolism. That’s when the body breaks down muscle tissue for energy rather than fat. Muscle strength decreases and leads to feelings of weakness. The process can also cause aches.

The reason that this same symptom occurs in patients with overactive thyroid glands is less clear. However, researchers suspect that excessive thyroid hormone levels can cause increased muscle protein degradation and muscle energy use. That will leave your muscles feeling sapped and weak.

10. Hair Loss
Hair follicles, like most cells, are regulated by thyroid hormone. Hair loss may occur with both hypothyroidism and hyperthyroidism because normal production of the hormones T3 and T4 is disrupted.

When this occurs, your natural hair loss (about 50-100 strands per day) is no longer replaced by fresh growth. The result is thinner hair overall, rather than noticeable bald patches. You may also notice it in your eyebrows and eyelashes.

Thyroid disorders are common and can be dangerous if left untreated. Unfortunately, none of the symptoms on their own are unique to thyroid conditions. Therefore, it is best to be aware of these symptoms as a group, especially if they show up suddenly at nearly the same time.

The good news is that thyroid conditions are highly treatable and the medication is relatively inexpensive. Don’t wait to talk to your doctor. Your quality of life can be greatly improved in no time with the right medical support.
