Experiencing abdominal pulsations can be concerning, especially when it is accompanied by other symptoms. The sensation of a pulsing or throbbing in the abdomen may be related to a variety of factors, and understanding these can help determine whether medical attention is necessary.

Firstly, it is important to recognize that the abdominal area contains several major blood vessels, including the aorta, which can sometimes be felt as a pulsation, especially in individuals with a thinner abdominal wall or in certain positions, such as lying down. This is often benign and can be a normal physiological phenomenon. However, if the pulsation is new, persistent, or accompanied by other symptoms such as pain, swelling, or changes in bowel or urinary habits, it may warrant further investigation.

In your case, since you mentioned that the pulsations occur when lying down and sometimes extend to the buttocks or legs, it is essential to consider the following potential causes:
1. Vascular Issues: Conditions such as an abdominal aortic aneurysm (AAA) can present with a pulsating sensation in the abdomen. This is a serious condition that requires immediate medical evaluation. Risk factors include age, smoking, hypertension, and a family history of vascular disease.

2. Muscle Spasms: Sometimes, the sensation of pulsation can be attributed to muscle contractions or spasms in the abdominal wall. This is generally less concerning but can be uncomfortable.

3. Gastrointestinal Motility: The intestines can also create sensations of movement or pulsation, especially after eating or during digestion. This is typically normal but can be more pronounced in some individuals.

4. Nerve Sensations: Conditions affecting the nerves in the abdomen can lead to unusual sensations, including pulsations. This could be related to previous surgeries, injuries, or conditions like fibromyalgia.

Given these possibilities, if the pulsations are accompanied by any of the following symptoms, it is advisable to seek medical attention promptly:
- Severe abdominal pain or discomfort
- Swelling or a noticeable mass in the abdomen
- Changes in bowel habits (such as diarrhea or constipation)
- Nausea or vomiting
- Changes in urinary habits or blood in urine
- Dizziness or fainting
In terms of which specialist to consult, starting with a primary care physician is a good approach. They can perform an initial evaluation, including a physical examination and possibly some basic imaging studies (like an ultrasound or CT scan) to assess for any vascular abnormalities or other underlying issues. If necessary, they may refer you to a specialist, such as a gastroenterologist for gastrointestinal concerns or a vascular surgeon if there are indications of vascular issues.

In summary, while abdominal pulsations can be benign, it is crucial to monitor any accompanying symptoms and seek medical advice if there are any concerning signs. Early evaluation can help rule out serious conditions and provide peace of mind.
