An inflamed body needs more pain medication because visceral fat and insulin resistance turn up pain signals. Long-term opioid therapy then feeds a loop. You lose muscle, insulin works worse, inflammation rises, and the dose climbs.
Two patients get the same injection into the same structure by the same physician. One is much better at six weeks. The other is not, and nothing about the procedure explains the gap.
What most often separates them is not the joint. It is the body the joint sits in. That same factor quietly decides how much pain medication a person ends up needing.
Can body fat cause inflammation and pain?
Visceral fat, the fat packed around the organs, pours interleukin-6, tumor necrosis factor alpha and other cytokines (inflammatory signals) straight into the blood that drains to the liver. Those signals do not stay local. They make the pain nerves in the body more sensitive. They also drive central sensitization in the dorsal horn of the spinal cord. That lowers the point at which the nervous system reports pain at all.
So a person with a high inflammatory load shows up with the volume already turned up. That is true before any structural injury is counted. The scan may show the same disc as the next person. The experience is not the same. Neither is the dose it takes to make it bearable.
Does insulin resistance make nerve pain worse?
High blood sugar cuts blood flow through the tiny vessels that feed nerves. Big swings in blood sugar track with how bad nerve pain gets, apart from the average level. A patient whose glucose swings widely can have worse nerve pain than their A1c predicts. That is one reason a number that looks fine on paper does not settle the question.
Put it together. The terrain decides how much pain a given structure makes. It also decides how well a repair placed into it will take. That is why the metabolic work here runs alongside a procedure, not after it.
Can long-term opioids make inflammation worse?
The link runs both ways. This is the part usually left out of the metabolic talk.
Long-term opioid therapy suppresses the hypothalamic-pituitary-gonadal axis, the hormone chain that controls sex hormones. The resulting low hormone state is well known in the literature. It is called opioid-induced androgen deficiency. Its known effects include low libido, fatigue, depression, loss of muscle mass, and lower bone density. Reviews of opioid-related hormone problems note the same effects. They add impaired fertility and osteoporosis.
Read that list next to the metabolic picture above and the overlap is plain. Lost muscle and fatigue cut activity. Less activity makes insulin work worse and raises inflammation. More inflammation lowers the pain threshold. A lower pain threshold raises the dose. It is a loop. In a patient who already has metabolic disease, it closes fast.
Can opioids make pain worse over time?
Long opioid use can also cause opioid-induced hyperalgesia. That is a resetting of the pain system toward more sensitivity. It is blamed on the central glutamatergic system and NMDA receptor activation, spinal dynorphin and descending facilitation. Where it is at work, more drug feeds the problem. One review calls further prescribing largely futile.
The flip side is the useful part. Reviews of tolerance and hyperalgesia make a point. Procedures that cut the pain input can let the dose fall. In doing so, they can reverse what drove it up. Treat the pain source, change the terrain it sits in, and the need falls as a result, not as a target.
Dr. Padda published his interventional practice’s own figures on that in August 2026. Patients arrived on an average dose above 90 morphine milligram equivalents a day after more than two and a half years in pain. 21% of patients were completely off opioid pain medication within 90 days of active treatment, and 34% within one year. Most of the rest held below 30 MME a day. Those are practice-reported figures from a single population, not trial outcomes, and individual results vary. Reported by AP News; full release.
What this changes about a plan
It puts two things on the same page that usually get treated as separate problems. Say someone carries a high metabolic and inflammatory load and a long-standing opioid need. Addressing either one alone tends to disappoint. The procedure underperforms in an inflamed body. And the dose will not come down while the terrain keeps making the signal.
It also sets a realistic pace. Inflammation and insulin sensitivity move over months, not weeks. The hormone effects of long-term opioid use do not reverse on the day the dose changes. A plan that assumes otherwise is setting up its own failure.
Frequently asked questions
What can cause chronic inflammation?
Visceral fat is a major source. The fat around the organs releases inflammatory signals such as interleukin-6 and tumor necrosis factor alpha into the blood, and they do not stay local. Insulin resistance adds to the load. Long-term opioid therapy can feed it too. It lowers hormones, costs muscle and cuts activity. That makes insulin work worse and raises inflammation further.
How do I know if my pain is caused by inflammation?
One clue is pain that is worse than the scan explains. Two people can show the same disc on imaging and live with very different pain, because inflammation turns up the volume of the nervous system before any injury is counted. Another clue is nerve pain worse than your A1c predicts. A third is a well-placed injection that underperforms.
How do you reduce pain caused by inflammation?
Treat the pain source and change the body it sits in at the same time. Addressing only one tends to disappoint. A procedure underperforms in an inflamed body. A medication dose will not come down while the terrain keeps making the pain signal. When both are treated, the need for medication falls as a result, not as a target.
What brings down inflammation quickly?
Nothing in this picture moves quickly. A plan that promises otherwise is setting up its own failure. Inflammation and insulin sensitivity change over months, not weeks. The hormone effects of long-term opioid use also do not reverse on the day the dose changes. Expect steady progress measured in months, with the procedure and the metabolic work running side by side.
