Red Blood in Stool – Causes and When to see a Doctor

It is vital for people with unexplained fatigue or other signs or symptoms of hypothyroidism to see a doctor. Without treatment, an underactive thyroid can lead to serious complications, such as infertility, obesity, and heart disease.

A doctor can carry out a simple blood test to check a persons thyroid hormone levels. Treatment for hypothyroidism involves taking synthetic thyroid hormones. These medications are safe and effective once a person takes the right dose.

Treat The Underlying Cause

If you have dysbiosis, a state of flora imbalance, SIBO, yeast, parasite or any other non-commensal critter growing in your gut it is vital that you treat them. Work with an experienced practitioner to re-establish healthy gut flora and restore your guts terrain to prevent future infections.

There are many natural therapies, including herbs, to use to bring your gut back to health. I caution you from beginning herbal antimicrobial therapy without medical supervision from a licensed health practitioner. Although they are natural, they can do quite a bit of damage when dosed incorrectly or for too long.

Hypothyroidism And Associated Gastrointestinal Diseases

Compared to the general population, patients with autoimmune thyroiditis have an almost 5-fold increased risk of developing celiac disease. Valentino et al showed that as many as 43% of patients with Hashimotos thyroiditis carry cellular markers for celiac disease. The prevalence of thyroid antibodies is extremely high in patients with pernicious anemia , and the prevalence of overt pernicious anemia among patients with primary hypothyroidism is 12%. An association between hypothyroidism and primary biliary cirrhosis is well documented and ranges from 5% to 20%. Among patients with primary biliary cirrhosis, antithyroid antibodies were present in 20%. The coexistence of Hashimotos thyroiditis and Crohns disease is rare and the etiological background remains to be elucidated.

Regular bowel movements contribute to good overall health by eliminating waste from the body. On the other hand, bowel movements that occur more frequently than usual may not only be uncomfortable , but may also indicate a health condition that could require treatment. For example, one of the most serious conditions that could potentially be the culprit is colon cancer, which can affect bowel function and may come with symptoms like persistent diarrhea, stomach pain, or a change in bowel habits.

To screen for colon cancer, consider trying our easy-to-use, at-home colon cancer test.

So if youâre experiencing more bowel movements than normal, hereâs a look at what causes frequent bowel movements, possible remedies that may help, and more.

Letâs start by discussing what frequent bowel movements are in the first place.

Black Tarry Or Bloody Stools

Black, tarry, or bloody stools are all a sign of blood loss. Poop color is a good reference point for a dog’s health, and any sign of blood in a dog’s stool requires immediate veterinary attention and cannot be delayed.

A black or tarry stool is caused by darker blood which is referred to as melena where a bright red blood in the stool is called hematochezia.

Melena has a jelly-like consistency and is darker in color because the blood has passed through the dog’s stomach or digestive tract. Darker blood indicates that the problem originates from the upper digestive tract.

Hematochezia is bright red blood and indicated that the bleeding originates in the dog’s colon or lower section of the digestive tract.

Dogs with blood in their stool may also exhibit other symptoms including:

  • Diarrhea
  • Vomiting
  • Appetite loss

Blood in the stool can result from a wide range of medications including anything that irritates the digestive tract.

Among the processes that may cause blood in the stool due to medication use are:

  • Colitis
  • Clotting factor changes

Which Doctor To Look For When Blood Appears In The Stool

Whoever has blood in the stool, should consult with a coloproctologist, specialist in diseases of the large intestine, rectum and anus. Immediate help is needed if you experience heavy bleeding, as well as symptoms such as dizziness and weakness.

At the consultation, the doctor will evaluate the symptoms, being able to do a digital rectal exam and also request specific exams to check what is behind the bleeding.

It is common for a person to undergo procedures such as an endoscopy to check for bleeding in the stomach or esophagus, and colonoscopy to check for abnormalities or diseases in the intestine.

The occult blood test may also be ordered to identify the presence of bleeding in the large intestine that does not appear to the naked eye. Also blood tests to see the person is not anemic due to frequent blood loss.

Treatments for bleeding in stools vary according to cause and severity.

Generally, medications are indicated to reduce the problem and make changes to the routine, such as avoiding straining during the bowel movement, drinking more water and changing the diet to increase fiber consumption.

In the case of colorectal cancer, treatments such as chemotherapy, radiation therapy or surgery are indicated.

The presence of blood in the stool indicates a warning sign. Some causes are common and easy to treat, such as hemorrhoids. However, if the condition persists, it is essential to seek medical help.

Performing The Transit Time Test

Food should pass through your intestines in 18-24 hours. If it takes longer than twenty-four hours, there is something wrong with your digestive tract. This easy to do test can be done at home to measure food transit time.

  • Purchase a product called âactivated charcoalâ which is an inert substance that will turn your stool black or dark gray.
  • Swallow four capsules with a meal and write down the day and time that you take the capsules.
  • Observe your stool until you see black or dark gray stool appear. At this point, write down the day and the time. Look at the time that you originally swallowed the capsules and the time that you see the dark stool and write down the total time it took for this to happen. If it took longer than twenty-four hours, you have some work to do on your digestive tract. If it took less than 18 hours, that may also be a problem meaning that there is something irritating the digestive tract causing increased peristalsis.

    Seeking Medical Care For Frequent Bowel Movements

    Changes to your bowel movement frequency are often temporary and may resolve on their own. However, it may be time to seek medical care if your bowel movements have become more frequent and/or if they are painful or uncomfortable.

    Itâs a good idea to make an appointment with your healthcare provider right away if you experience any of the following symptoms with frequent bowel movements:

    Sibo Can Make Hypothyroidism Worse

    Weve established that patients with hypothyroidism may suffer from decreased stomach acid and impaired motility, which may result in the formation of SIBO over time. But can SIBO actually worsen hypothyroid?

    We do know that an overgrowth of bacteria can interfere with levothyroxine absorption. This means that even those who are diagnosed with hypothyroid and taking a thyroid replacement hormone may not be receiving the intended dose of thyroid hormone.

    SIBO, Leaky Gut and Autoimmunity

    We also know that damage in the small intestine is closely related to autoimmune diseases of all kinds. Leaky gut or intestinal permeability and SIBO are closely linked, and leaky gut is found in all cases of autoimmunity.

    Damage in the small intestine can lead to immune activation, food particles in the bloodstream, and ultimately, a systemic problem that can result in autoimmunity or perpetuate the immune systems attack on healthy tissues.

    Recognizing The Signs Of Constipation

    Since everyone is different, there really is no right or wrong when it comes to the number of bowel movements you should have. However, signs that indicate constipation include:

    • Having three bowel movements a week
    • Passing dry, hard, or lumpy stools
    • Producing stools you have to strain to pass
    • Having painful bowel movements
    • Feeling as if you have a blockage or incomplete bowel movement

    Your thyroid regulates many of your bodily functions, including digestion and elimination. Without enough thyroid hormone in your system, your gastrointestinal tract may not work properly, leading to constipation.

    What Are Early Warning Signs Of Thyroid Problems


    Your thyroid is a small gland that produces hormones. Under some circumstances, this gland may begin to produce too many thyroid hormones. This issue is called hyperthyroidism. In contrast, this gland will produce an insufficient amount of hormones if you develop hypothyroidism. There are several early warning signs that may indicate that you have developed one of these thyroid issues.

    If you are experiencing these problems, you should schedule a thyroid test at our office in Louisville. After we diagnose your problem, we can recommend medications and other treatments that will relieve your symptoms and enhance your health.

    Why Does Hypothyroidism Cause Constipation

    As seen throughout this post, current evidence confirms the relationship between constipation and hypothyroidism. Youre probably wondering why that happens in the first place. While exact mechanisms arent fully investigated, the culprit could be the fact that insufficient levels of thyroid hormones slow down the bodys functions.

    Just like the above-mentioned studies revealed, hypothyroidism slows function of digestive tract thus causing irregular bowel movements or making it difficult for a person to eliminate waste from the body.

    Moreover, digestive tract including both large and small intestine are lined with muscles. The proper function of these muscles is important for healthy digestion and bowel movements. In order to move waste or stool through the intestine to the rectum and out of the body, muscles need to contract.

    Due to hypothyroidism contraction of muscles slows down and weakens. As a result, stool also moves slowly, and you experience infrequent bowel movements or difficulty passing stool.

    Not only is constipation uncomfortable and frustrating, particularly when its chronic, but it can also decrease the efficacy of medications youre taking. After all, therapy needs to be fully absorbed in order to work, but digestion-related problems like constipation impair absorption.

    This only emphasizes the importance of management of constipation.

    The 4 Rs To Repair Gastrointestinal Dysfunction:

    • Remove: Eliminate known food allergens such as gluten, dairy, eggs, soy, peanuts, etc. I do blood testing on patients for food sensitivities to pinpoint food reactions. Alcohol, caffeine and NSAIDS should be avoided as well. A stool analysis will diagnose infections that can be eliminated with natural medicines or medications.
    • Repair: Supplements to repair the intestinal barrier are taken.
    • Replace: Hydrochloric acid and pancreatic enzymes offer digestive support.
    • Reinoculate: Probiotics that contain friendly bacteria such as lactobacillus and bifidobacter are taken to reinoculate proper bacterial colonies. I will also educate every patient on specific foods that can help to rebuild your healthy gut bacteria.

    What Are The Symptoms Of Hyperthyroidism

    The symptoms of hyperthyroidism can vary from person to person and may include

    • Nervousness or irritability
    • Imaging tests, such as a thyroid scan, ultrasound, or radioactive iodine uptake test. A radioactive iodine uptake test measures how much radioactive iodine your thyroid takes up from your blood after you swallow a small amount of it.

    The signs in children are different from those in adults. The most common sign in children is slowed or delayed growth. This may occur years before other signs occur. Other signs can occur a bit differently in each child, and can vary by age.

    Signs in younger children can include:

    • Slow growth that may cause short limbs

    • Delayed tooth development

    • Inactivity

    • Slow bowel movements

    The symptoms of hyperthyroidism can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

    Key Points About Hypothyroidism In A Child

    • Hypothyroidism is when the thyroid gland doesn’t make enough thyroid hormone. Its the most common thyroid disorder in children.

    • Not enough thyroid hormone leads to signs such as slow growth, lack of activity, and poor performance in school.

    • The most common cause is an autoimmune reaction that destroys the thyroid gland.

    • Treatment may include taking thyroid hormones to increase the level of hormones in the body. Some children will need to take hormones for life. Other children may outgrow the disorder.

    • Hypothyroidism can impair a child’s normal growth and development. Its important for a child to continue treatment until after puberty. This will help ensure a child reaches his or her normal adult height.

    Who Is At Risk For Hyperthyroidism

    You are at higher risk for hyperthyroidism if you

    • Are a woman
    • Are older than age 60
    • Have been pregnant or had a baby within the past 6 months
    • Have had thyroid surgery or a thyroid problem, such as goiter
    • Have a family history of thyroid disease
    • Have pernicious anemia, in which the body cannot make enough healthy red blood cells because it does not have enough vitamin B12
    • Have type 1 diabetes or primary adrenal insufficiency, a hormonal disorder
    • Get too much iodine, from eating large amounts of foods containing iodine or using iodine-containing medicines or supplements

    With most treatments, there are also risks of side effects. Its important to talk to your healthcare provider and weigh all of the pros and cons before deciding on a treatment plan. Some of these risks include:

    After treatment, you will most probably need to take replacement thyroid hormone for the rest of your life. This is because some of these treatments especially surgery reduce your thyroid hormone levels to very low levels or eliminate this hormone by removing your thyroid. Youll need to re-introduce the thyroid hormones back into your system by taking regular medication.

    Hyperthyroidism And Associated Gastrointestinal Diseases

    Chng et al found that patients with Graves disease were at a 5-fold added risk of developing celiac disease when compared to sex- and age-matched controls. In such cases, celiac disease may contribute to diarrhea and malabsorption. Thyrotoxicosis has been reported in 3.8% of patients with ulcerative colitis while the incidence of ulcerative colitis in hyperthyroid patients varies around 1%. Thyroid disease may exacerbate ulcerative colitis symptoms or alter the response to therapy. Moreover, a positive correlation between Graves disease and ulcerative colitis has been reported, but a common autoimmune origin could not be proven. Isolated instances of an association between Graves disease and Crohns disease have been reported, but a common pathogenesis is still to be identified. Primary biliary cirrhosis in association with hyperthyroidism is extremely rare and has only described as isolated case reports. One study showed a prevalence of pernicious anemia of 5% in thyrotoxic patients, mainly resulting from Graves disease, but parietal cell antibodies have been found in up to 30% of patients.

    Constipation And Hypothyroidism In Children

    Despite the fact that constipation is a common concern, most people feel uncomfortable talking about it. Thats why we dont see many articles and hypothyroidism-related blogs discussing this subject. However, in order to manage your condition properly, it is important to address even those things that one may find embarrassing.

    The relationship between constipation and hypothyroidism is not explored as well as it should be. Bennett W.E. et al explored the prevalence of hypothyroidism among children with constipation and found that only a small portion of children with this gastrointestinal concern had problems with the underactive thyroid gland.

    That means that hypothyroidism is an unlikely cause of constipation in hypothyroid children. That being said, it is recommended that children with severe constipation undergo thyroid hormone evaluation.

    Goto S. et al explain that hypothyroidism may be associated with either severe constipation or megacolon that mimics Hirschsprungs disease, a condition that affects large intestine and impairs passing of the stool. Hirschsprungs disease is present at birth i.e., and it is a congenital condition that occurs due to missing nerve cells in the babys colon.

    However, the mechanisms underlying this relationship are not very clear, scientists report.
