Constipation can potentially lead to feelings of nausea.
### Common Links Between Constipation and Nausea
Constipation and nausea are often interconnected, with their shared roots typically found in conditions that affect the digestive system's function and motility. In this article, we explore the common causes linking these two symptoms and the underlying medical conditions that might be involved.
#### Digestive Disorders
One of the primary causes of both constipation and nausea is Irritable Bowel Syndrome (IBS). IBS frequently presents with symptoms of constipation (IBS-C), nausea, abdominal pain, bloating, and cramping. People with IBS may experience disrupted bowel movements and nausea due to altered gut motility and sensitivity [1][4].
#### Food Intolerances and Sensitivities
Conditions such as celiac disease, lactose intolerance, or dairy protein sensitivity can cause abdominal discomfort, constipation, and nausea as part of the body's reaction to certain foods [1].
#### Infections and Inflammation
Intestinal infections or inflammation can disrupt bowel function, causing constipation, and may also trigger nausea and vomiting [1].
#### Pelvic Floor Dysfunction and Obstructions
Problems with the pelvic floor muscles or physical obstructions in the colon or rectum (such as strictures, tumors, or severe hemorrhoids) can cause stool build-up, resulting in constipation and secondary nausea due to digestive stasis or discomfort [2].
#### Medications and Lifestyle Factors
Certain medications, including painkillers, antidepressants, iron supplements, dehydration, low fiber intake, and lack of physical activity, can lead to constipation and may also induce nausea through slowed digestion or gastrointestinal irritation [2][3].
### Underlying Medical Conditions
#### Irritable Bowel Syndrome (IBS)
IBS is a functional gastrointestinal disorder characterized by alternating bowel habits (constipation or diarrhea), abdominal pain, and nausea. Both IBS-C and IBS-D can involve nausea, with IBS-C specifically linked to constipation [1][4].
#### Hypothyroidism
Hypothyroidism can slow metabolic and digestive processes, leading to chronic constipation and sometimes nausea [3].
#### Neurological Disorders
Conditions such as multiple sclerosis or spinal cord injury can impair nerve signals to the bowel and contribute to constipation and nausea [3].
#### Endocrine Imbalances
Hormonal changes (e.g., pregnancy, hormonal disorders) can affect gut motility, resulting in constipation and nausea [3].
#### Gastrointestinal Obstruction
Colon or rectal obstruction due to tumors, strictures, volvulus, or severe hemorrhoids may cause constipation with nausea and vomiting due to blockage [2].
#### Food Intolerances
Celiac disease and lactose intolerance involve immune or enzymatic reactions causing nausea, abdominal pain, and changes in bowel habits, including constipation [1].
In summary, constipation and nausea often coexist due to shared underlying digestive dysfunctions, infections, obstructions, or systemic medical conditions that impair normal gut motility and function. Identifying the precise cause requires evaluating the whole clinical context, including diet, lifestyle, medications, and other symptoms like abdominal pain or bloating. If persistent, these symptoms warrant medical assessment to exclude serious conditions like bowel obstruction or metabolic disorders.

- Nausea and nausea can stem from similar medical conditions that impact the digestive system's function, such as Irritable Bowel Syndrome (IBS), hypothyroidism, and neurological disorders.
- Food intolerances, including celiac disease and lactose intolerance, can cause both nausea and changes in bowel habits, like constipation.
- Furthermore, disruptions in digestive health, fitness, and exercise routines, or inadequate nutrition, can lead to constipation and indirectly cause nausea.
- Health-and-wellness practices involving proper diet, regular physical activity, and possibly medical intervention can help manage nausea and constipation associated with various medical conditions.
