How Your Thyroid affects Stomach Acid and causes Bloat

How Your Thyroid affects Stomach Acid and causes Bloat

Thyroid disorders can disrupt the digestive processes. For example, hypothyroidism (low thyroid hormone levels) can further lead to a slowdown in metabolism, constipation, reduced appetite, low stomach acid and bloating. If you're suffering from any of these symptoms your thyroid might be to blame.

The thyroid is a small, butterfly-shaped gland located in the front of the neck, just below the Adam's apple. It is part of the endocrine system, which is responsible for producing and regulating hormones in the body. The thyroid gland plays a crucial role in controlling various bodily functions by releasing hormones that influence metabolism, growth, and development.

The thyroid gland plays a crucial role in regulating metabolism throughout the body, including the digestive system. It does so through the production and release of two main hormones: thyroxine (T4) and triiodothyronine (T3). These hormones are produced in response to signals from the brain's pituitary gland, which releases thyroid-stimulating hormone (TSH) to stimulate the thyroid.


Here's how the thyroid gland affects digestion:

1. **Metabolism Regulation: The thyroid hormones T4 and T3 influence the body's basal metabolic rate (BMR), which is the amount of energy your body needs to function at rest. A higher BMR means that the body's cells are working at a faster rate, which can lead to an increase in digestive processes.

2. **Gut Motility: Thyroid hormones can influence the muscles of the digestive tract. When thyroid function is optimal, it helps maintain a healthy balance of muscle contractions in the intestines. This regulates the movement of food and waste through the digestive system.

3. **Absorption of Nutrients: Adequate levels of thyroid hormones are necessary for the absorption of nutrients from the food you eat. This includes vital nutrients like vitamins, minerals, and macronutrients (carbohydrates, proteins, and fats).

4. **Enzyme Production: The thyroid hormones influence the production of digestive enzymes. Enzymes are essential for breaking down food into smaller molecules that can be absorbed by the body.

5. **Stimulation of the Liver: Thyroid hormones can stimulate the liver, which is a crucial organ in the digestive process. The liver produces bile, which is necessary for the breakdown and absorption of fats.

6. **Regulation of Appetite: Thyroid hormones can influence appetite. An overactive thyroid (hyperthyroidism) can lead to an increased appetite, while an underactive thyroid (hypothyroidism) may lead to a decreased appetite.

7. **Maintaining Gut Health: Proper thyroid function is important for overall gut health. An imbalance in thyroid hormones can lead to issues like constipation, diarrhea, or other gastrointestinal problems. A good probiotic like ThyVita Digestives can help ease some of the symptoms of bloat and promote weight loss.


It's important to note that if there is a thyroid disorder, such as hypothyroidism or hyperthyroidism, it can disrupt these processes. For example, hypothyroidism (low thyroid hormone levels) can further lead to a slowdown in metabolism, constipation, and reduced appetite, while hyperthyroidism (excessive thyroid hormone levels) can lead to an increase in metabolism, diarrhea, and an increase in appetite.

Research show most thyroid patients experience low stomach acid levels, a condition known as hypochlorhydria. This can be due to various reasons related to thyroid dysfunction:


1. **Hormonal Imbalance: The thyroid gland plays a crucial role in regulating the body's metabolism, which includes the production and regulation of various hormones. When the thyroid is not functioning optimally, it can lead to imbalances in other hormonal systems, which can indirectly affect stomach acid production.

2. **Reduced Gastric Motility: Thyroid disorders can affect the motility (movement) of the gastrointestinal tract. Slower movement can lead to a decrease in gastric acid production and bloating.

3. **Nerve Function: Thyroid hormones influence the function of nerves throughout the body, including those that control the digestive system. When thyroid function is disrupted, it can affect the signals that stimulate stomach acid production.

4. **Autoimmune Conditions: Certain thyroid disorders, such as Hashimoto's thyroiditis, are autoimmune conditions. These can have systemic effects on the body, potentially including the digestive system.

5. **Nutrient Absorption: Low stomach acid can lead to poor absorption of essential nutrients, which can exacerbate thyroid issues and create a feedback loop.

6. **Medications: Some medications used to treat thyroid disorders may indirectly affect stomach acid levels.


It's important to note that while low stomach acid can be a symptom of thyroid dysfunction, it's not a universal experience for all thyroid patients. Additionally, not all cases of low stomach acid are directly related to thyroid problems; other factors, such as diet, stress, and age, can also play a role.

If you suspect you have low stomach acid or are experiencing symptoms related to thyroid dysfunction, it's crucial to consult with a healthcare professional. They can perform appropriate tests and provide tailored advice and treatment.

My eyebrows fall off. I thought that it was due to stress. Then after thyroid check, the doctor said I have thyroid nodules. I had Fine needle aspiration twice, The doctor said,,if the nodules get bigger, my thyroid should be taken out. I’m in the process of looking for a new doctor now. Does this vitamin help?
