Goiter: Causes, Symptoms, Treatment and Prevention
What is golter?
A goiter or goitre is a swelling or large mass on the throat that results from abnormal growth of a gland called the thyroid.It is one of the most common thyroid disorders.
Goiters are often harmless but symptoms can occur, and treatment may be required depending on the size and type of goiter.
The thyroid gland is situated in front of the windpipe and is responsible for producing and secreting hormones that regulate growth and metabolism.
Causes of goiter
Most goiters is caused by lack of iodine in the diet. Also, a lack of iodine in a pregnant woman's diet sometimes causes babies to die or born mentally slow and maybe deaf (is called cretinism). This can happen even though the mother does not have a goiter.
As iodine is less commonly found in plants, vegan diets may lack sufficient iodine. This is less of a problem for vegans who live in countries such as the United States that add iodine to salt.
Dietary iodine is found in:
Other causes
Less common causes of goiter include the following:
Most goiters has no symptoms. But symptoms do occur, the following are most common:
As iodine is less commonly found in plants, vegan diets may lack sufficient iodine. This is less of a problem for vegans who live in countries such as the United States that add iodine to salt.
Dietary iodine is found in:
- seafood
- plant food grown in iodine-rich soil
- cow's milk
Other causes
Less common causes of goiter include the following:
- Smoking: Thiocyanate in tobacco smoke interferes with iodine absorption.
- Hormonal changes: Pregnancy, puberty, and menopause can affect thyroid function.
- Thyroiditis: Inflammation caused by infection, for example, can lead to goiter.
- Lithium: This psychiatric drug can interfere with thyroid function.
- Overconsumption of iodine: Too much iodine can cause a goiter.
- Radiation therapy: This can trigger a swollen thyroid, particularly when administered to the neck.
Signs and Symptoms of goiter
The degree of swelling and the severity of symptoms produced by the goiter depends on the individual.Most goiters has no symptoms. But symptoms do occur, the following are most common:
- throat symptoms of tightness, cough, and hoarseness
- trouble swallowing
- in severe cases, difficulty breathing, possibly with a high-pitch sound
Other symptoms may be present because of the underlying cause of the goiter, but they are not because of the goiter itself. For example, an overactive thyroid can cause symptoms such as:
- nervousness
- palpitations
- hyperactivity
- increased sweating
- heat hypersensitivity
- fatigue
- increased appetite
- hair loss
- weight loss
In cases where goiter is a result of hypothyroidism, the underactive thyroid can cause symptoms such as:
- cold intolerance
- constipation
- forgetfulness
- personality changes
- hair loss
- weight gain
Aside from the swelling itself, many people with goiter present no symptoms or signs at all.
Treatment and Prevention goiter
Everyone that want to live healthy should use iodized salt. This also prevent people in areas where goiters do occur and will help many goiters go away. (Old, hard goiters can only be removed by surgery, but this is not usually necessary.)
- If it is not possible to get ionized salt, use tincture of iodine.
- Put 1 drop in a glass of water each day and drink. Be careful. Too much tincture of iodine is poisonous.
- Drink only 1 drop a day keep the bottle where children can not reach it. Iodized salt is much safer.
Avoid eating cassava if you are in area where goiters are common.
Hypothyroidism
In case of thyroid or hypothyroidism, treatment is usually synthetic replacement of thyroid hormone.
The dosage of synthetic thyroxine (T4) is gradually increased until measurements indicate normal thyroid function has been restored.
Hyperthyroidism
In goiters caused by overactive thyroid or hyperthyroidism, treatment aims to counter the excess hormone production. For instance, anti-thyroid drugs, such as thionamide drugs, gradually reduce excessive hormone levels.
Radioactive iodine to decrease thyroid function and stop hormone production is also a treatment option for hyperthyroidism.
Goiter surgery
Surgery to reduce the size of swelling if their is difficulty breathing or swallowing.
Thyroidectomies are performed under general anesthetic to remove part of the thyroid gland.
Types of Goiter
There are several main types of goiter:
- Diffuse smooth goiter: This occurs when the entire thyroid swells.
- Nodular goiter: A lump develops on the thyroid. These are extremely common. If any lumps develop, this is known as multinodular goiter.
- Retrosternal goiter: This type of goiter can grow behind the breastbone. This can constrict the windpipe, neck veins, oesophagus, and sometimes requires surgery.
The type of goiter will dictate how it is treated and the symptoms that may show.
Prevention of goiter
- Never use regular salt
- Always use iodized salt
If a person with a goiter tremble a lot, is very nervous, and has eyes that bulge out, this may be a different kind of goiter (toxic goiter). Seek medical advice immediately.
