High Bp? Natural Constipation Relief

Constipation and high blood pressure are linked, with studies showing that constipation is associated with an increased risk of hypertension. Certain medications for high blood pressure can cause constipation, including calcium-channel blockers, beta-blockers, and diuretics. Additionally, some medications for other conditions, such as antidepressants, opioids, and anticholinergics, can also lead to constipation. To relieve constipation, it is recommended to increase fibre intake, stay hydrated, and use laxatives or over-the-counter remedies. Lifestyle interventions, such as regular exercise, can also help.

Opioid medications, such as oxycodone, can cause constipation by inhibiting movement in the gut

Opioids work by activating three types of opioid receptors: mu, delta, and kappa. In the gut, mu and delta receptors are the most common and are found in the myenteric and submucosal plexus. When opioids activate these receptors, they inhibit the release of acetylcholine, a chemical that helps the gut muscles move. This leads to a decrease in gut motility, making it harder for food to move through the intestines. Opioids also increase the absorption of fluid in the intestines, which can lead to harder stools and further contribute to constipation.

The risk of developing OIC increases with the duration of opioid therapy. It can develop immediately after starting opioid medication or gradually during therapy. OIC often persists even after reducing the opioid dose or discontinuing the medication. This is because tolerance to the constipating effects of opioids does not develop over time, unlike other side effects such as nausea and vomiting.

To prevent OIC, it is recommended to start laxatives at the same time as opioid therapy. However, bulk-forming laxatives like psyllium should be avoided as they can worsen abdominal pain and contribute to bowel obstruction. Other types of laxatives, such as stimulant laxatives (e.g. senna/bisacodyl) and stool softeners (e.g. docusate), are typically used to treat OIC. Increasing dietary fiber, fluid intake, and physical activity can also help prevent and manage OIC.

In summary, opioid medications like oxycodone can cause constipation by slowing down movement in the gut. This is due to the activation of opioid receptors, primarily mu and delta, which inhibits the release of acetylcholine and decreases gut motility. Preventative measures and treatments are available, but OIC can be challenging to manage and may persist even after reducing or stopping opioid medication.

Calcium-channel blockers, like diltiazem, can lead to constipation by relaxing the muscles in the gut

Calcium-channel blockers, such as diltiazem (Cardizem), are medications that treat high blood pressure and other heart-related health conditions. They work by relaxing the smooth muscles in blood vessels to lower blood pressure. Unfortunately, they also relax the muscles in the gut, which can lead to constipation. Constipation occurs when bowel movements become difficult or infrequent.

Constipation is a common side effect of many medications, and calcium-channel blockers are no exception. This side effect is thought to be connected to how these drugs work. While they relax the smooth muscles in blood vessels, they can also relax the stomach muscles, contributing to constipation. Of the calcium-channel blockers, verapamil and diltiazem are the biggest culprits for causing constipation, with up to 11% of people experiencing this side effect while taking verapamil.

If you are taking a calcium-channel blocker and experiencing constipation, there are ways to help ease this unwanted side effect. Adjusting your diet to include plenty of fibre, staying well-hydrated, and getting regular exercise can help manage constipation. Additionally, several over-the-counter (OTC) laxatives are available to provide short-term relief. However, it is important to talk to your healthcare provider to determine if an OTC laxative is suitable for you.

It is worth noting that constipation can be frustrating and impact your quality of life. Before blaming your diet, consider whether medication side effects are causing your constipation. If you are taking multiple medications, they could be making constipation worse. Older adults may be more susceptible to the constipation side effects of medications due to natural ageing or digestive system imbalances. Therefore, it is crucial to consult your doctor if you are experiencing constipation symptoms, such as infrequent bowel movements (typically fewer than three times a week), hard or small, lumpy stools, straining, painful bowel movements, or the sensation of incomplete emptying after a bowel movement.

Anticholinergics, found in many over-the-counter and prescription medications, block acetylcholine, reducing gut movement

Anticholinergics are a large class of medications found in many over-the-counter and prescription medications. They are drugs that block the action of acetylcholine, a neurotransmitter or chemical messenger that transfers signals between certain cells to affect how your body functions. By blocking acetylcholine, anticholinergics inhibit parasympathetic nerve impulses, which are responsible for involuntary muscle movements in the gastrointestinal tract and other parts of the body. This includes reducing gut movement, which can lead to constipation.

Anticholinergics are used to treat a wide range of health conditions, including urinary incontinence, overactive bladder, chronic obstructive pulmonary disease (COPD), certain types of poisoning, and symptoms of Parkinson's disease. They are also used before surgery to help maintain body functions while a person is under anesthesia.

While anticholinergics can be effective in treating various conditions, they can also cause side effects, especially in older adults. Side effects may include decreased urination, digestion, and secretion of mucus and saliva. Anticholinergics can also cause confusion, memory loss, and worsening mental function in people over 65 years of age. In fact, studies have linked the use of anticholinergics to an increased risk of dementia.

It is important to note that people with certain conditions should avoid using anticholinergics, including those with high blood pressure (hypertension), urinary tract blockage, and increased heart rate (tachycardia). Additionally, older adults are more susceptible to the constipation side effects of medications due to age-related changes in their digestive system.

If you are experiencing constipation and high blood pressure, it is important to consult your doctor to determine the most appropriate treatment option for your specific situation.

Antidepressants, such as fluoxetine, can affect nerve endings in the gut, leading to constipation

Antidepressants are a common cause of constipation. Certain antidepressants, such as fluoxetine (Prozac), are known to affect nerve endings in the gut, which can lead to significant side effects, including constipation.

Fluoxetine is a type of selective serotonin reuptake inhibitor (SSRI) that works by increasing serotonin levels in the brain. While SSRIs are generally considered to have fewer side effects than other types of antidepressants, constipation can still occur in some people. In addition to fluoxetine, other SSRIs that have been associated with constipation include escitalopram and venlafaxine.

The gut is lined with nerve endings that play a crucial role in regulating bowel movements. When antidepressants like fluoxetine affect these nerve endings, it can disrupt the normal functioning of the gut, leading to constipation. This is because the nerve endings in the gut are involved in controlling the muscular contractions that propel waste matter through the digestive tract. By altering the nerve signals, fluoxetine can slow down these contractions, making it difficult for waste to move through the intestines, resulting in constipation.

Additionally, fluoxetine and other SSRIs can impact the production of intestinal secretions that lubricate the passage of feces. When these secretions are reduced, it can lead to drier stools, making them harder to pass and contributing to constipation.

It is important to note that while fluoxetine and other antidepressants can cause constipation, they may also be prescribed to treat certain gastrointestinal conditions. For example, tricyclic antidepressants, such as amitriptyline (Elavil), are sometimes used to slow activity in the digestive tract for conditions such as diarrhea and irritable bowel syndrome (IBS). However, when taken by individuals with no gastrointestinal issues, these medications can have the opposite effect, leading to constipation.

Iron supplements are associated with constipation, often causing darker stools

Iron supplements are known to cause constipation, along with other gastrointestinal symptoms. They can also lead to darker stools, which can be concerning for individuals taking them regularly. However, it is important to understand the reason behind this colour change.

Iron supplements typically contain iron in ionic forms, such as ferrous sulfate, ferrous gluconate, or ferrous fumarate, which the body directly absorbs. However, the body can only absorb a limited amount of iron at once, and any excess remains in the digestive tract. This unabsorbed iron in the gut can react with other compounds, such as sulfur-containing amino acids or hydrogen sulfide produced by gut bacteria, forming non-absorbed iron complexes. These complexes are responsible for the black colour of the stool, making it appear dark or black.

It is worth noting that the colour change in stools is not a cause for concern and is a common side effect of iron supplements. In fact, it indicates that your body is absorbing the supplement. If you do not notice any changes in stool colour after taking short-term iron supplements, it may be a sign that your body is not absorbing the iron effectively. In such cases, it is advisable to consult a doctor or pharmacist to recommend an alternative brand or type of supplement.

While the darkened stool colour itself is not dangerous, it is important to pay attention to other symptoms that may accompany it. For instance, if the black stool is accompanied by symptoms such as abdominal pain, nausea, vomiting, fatigue, or weakness, it could indicate gastrointestinal bleeding or other serious conditions. Therefore, it is recommended to consult a healthcare provider if you experience any troubling symptoms along with the colour change in your stools.

To summarise, iron supplements are associated with constipation and can cause darker stools due to excess iron in the digestive tract. While the colour change is generally harmless, it is important to be vigilant about any accompanying symptoms and consult a healthcare professional if concerned.
