Persistent Warm Sensation in Hands, Feet, and Stomach: Causes and Concerns - Family Medicine

The sensation of persistent warmth in the hands, feet, and stomach can be concerning, especially when it has been ongoing for an extended period, as you described. Your experience of feeling warm in these areas, with a body temperature hovering around 37 to 37.5 degrees Celsius, suggests that while you may not have a fever, there is still an abnormal sensation that warrants further exploration.

Firstly, it is essential to consider the potential causes of this persistent warmth. One possibility is that it could be related to a condition known as peripheral neuropathy, which can manifest as abnormal sensations in the extremities. This condition can arise from various factors, including diabetes, vitamin deficiencies, or even certain medications. However, since you mentioned that you have had thyroid function tests that returned normal results, it is less likely that hyperthyroidism is the cause, as this condition typically presents with additional symptoms such as weight loss, increased heart rate, and anxiety.

Another potential cause could be related to autonomic nervous system dysfunction, which can lead to abnormal temperature regulation. This dysfunction might cause certain areas of the body to feel warmer than others, even in the absence of an actual increase in core body temperature. Conditions such as dysautonomia or small fiber neuropathy could be considered, especially if you have experienced any changes in sweating patterns or other autonomic functions.

Infections can also lead to localized warmth, but given that you have undergone testing and found no signs of infection, this seems less likely. However, it is still worth considering that some infections can be subtle and may not always present with classic symptoms. If you have any concerns about this, further testing, including blood tests to check for inflammatory markers or other signs of infection, could be beneficial.

Additionally, anxiety and stress can manifest physically in various ways, including changes in body temperature perception. If you have been experiencing heightened anxiety or stress, this could contribute to your sensations of warmth. The mind-body connection is powerful, and psychological factors can significantly influence physical sensations.

It is also important to consider lifestyle factors that could contribute to your symptoms. For instance, diet, hydration, and physical activity levels can all impact how your body regulates temperature. Ensuring that you are well-hydrated and consuming a balanced diet rich in vitamins and minerals can support overall health and potentially alleviate some of the sensations you are experiencing.

Given that your symptoms have persisted for over a year, it would be advisable to follow up with a healthcare provider who can conduct a thorough evaluation. This may include a detailed neurological examination, additional blood tests, or referrals to specialists such as a neurologist or an endocrinologist, depending on the findings. Keeping a symptom diary, noting when the sensations occur and any associated factors, can also provide valuable information for your healthcare provider.

In summary, while the persistent warmth in your hands, feet, and stomach may not indicate an acute medical emergency, it is essential to investigate further to rule out any underlying conditions. A comprehensive approach that considers both physical and psychological factors will likely yield the best results in understanding and addressing your symptoms.
