BEAM, Circuit Judge.
Homer H. Sanders appeals the judgment of the district court affirming the Secretary's denial of social security disability benefits. We reverse and remand for further proceedings.
Following a hearing, the ALJ determined that the medical evidence established that Sanders had severe hypertension, which could be controlled by medication, generalized arthritis, somatoform pain disorder, and dysthymia. He found that Sanders's subjective allegations of severe pain, weakness, nervousness, and physical limitations were not credible to the extent alleged. The ALJ found that Sanders could not perform his past relevant work as a farmer or factory worker, but that he had the residual functional capacity to perform sedentary work.
Because the ALJ determined that Sanders was unable to return to his past relevant work, the burden shifted to the Secretary to show that Sanders was able to engage in work in the national economy. McCoy v. Schweiker, 683 F.2d 1138, 1147 (8th Cir.1982) (en banc). The ALJ used the Guidelines as a framework for his decision that Sanders was not disabled, without resorting to vocational expert testimony. "[A]n ALJ may use the Guidelines even though there is a nonexertional impairment if the ALJ finds, and the record supports the finding, that the nonexertional impairment does not diminish the claimant's residual functional capacity to perform the full range of activities listed in the Guidelines." Thompson v. Bowen, 850 F.2d 346, 349-50 (8th Cir.1988). However, if the claimant's nonexertional impairments diminish his or her residual functional capacity to perform the full range of activities listed in the Guidelines, the Secretary must produce expert vocational testimony or other similar evidence to establish that there are jobs available in the national economy for a person with the claimant's characteristics. Id. at 349. "Nonexertional limitations are limitations other than on strength but which nonetheless reduce an individual's ability to work." Asher v. Bowen, 837 F.2d 825, 827 n. 2 (8th Cir.1988). Examples include "mental, sensory, or skin impairments, as well as impairments which result in postural and manipulative limitations or environmental restrictions." Id.; See 20 C.F.R., Pt. 404, Subpt. P, App. 2, § 200.00(e) (1992).
We conclude that Sanders's nonexertional impairments are significant enough to diminish his residual functional capacity to perform the full range of work contemplated by the Guidelines. Dr. Adam T. Brazas, a consulting psychologist, diagnosed somatoform pain disorder and dysthymia, and warned that stress would likely exacerbate Sanders's somatic complaints. The ALJ did not require further
Accordingly, we reverse and remand to the Secretary for further proceedings.
